stalagmite
Enable an AI agent to recognise a stalagmite, assess its growth and physical condition, and determine which observation, protection or sampling actions are appropriate.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a stalagmite, assess its growth and physical condition, and determine which observation, protection or sampling actions are appropriate.
A stalagmite is a secondary cave mineral deposit (speleothem) that grows upward from a cave floor or other substrate by precipitation of dissolved minerals, typically calcite, from dripping or splashing water.
It can be Identify and map the formation using photographs, measurements and its cave location.; Monitor drip delivery, surface wetness and repeat surface measurements to assess change.; Assess visible attachment and fractures to guide expert inspection and protective access controls.; Evaluate whether internal growth records could answer a stated research question.; Select minimally disturbing observation methods and, where authorised, justify sampling locations and limits..
Distinguishing features
Establish that the formation grew upward from a floor or supporting substrate; hanging downward from a ceiling identifies a stalactite instead.
Look for a localised buildup associated with drip deposition; a coating or sheet following water flow across a surface suggests flowstone instead.
Check whether the formation remains separate from an overhead deposit; a continuous floor-to-ceiling connection requires a boundary decision with a column model.
Verify mineral deposition rather than identifying a similarly shaped ice mass, sediment mound or carved object solely by silhouette.
For a detached or overturned object, require contextual or internal evidence of its original upward growth rather than relying on its present orientation.
Scope
+ Evidence identifying the object as a stalagmite and delimiting its physical extent
+ Geometry, growth axes, basal attachment and relationships to adjacent deposits
+ Mineral composition, internal layering and evidence of deposition or dissolution
+ Relationships between incoming drips, surface wetness and local growth conditions
+ Physical damage, conservation constraints and suitability for observation or sampling
- The cave system's overall geometry, access routes and management
- Regional groundwater circulation and catchment processes
- Stalactites, flowstone and joined columns as independently identified formations
- Laboratory instruments, analytical procedures and detached sample custody
- Regional climate reconstructions derived from multiple geological records
Characteristics
- Identification confidence
- confirmed | probable | unresolved, with supporting observations Prevents shape alone from establishing identity when origin or orientation is uncertain.
- Dimensions and profile
- height and widths in mm or m, with measurement axis and observation date Supports recognition, repeat comparison and assessment of accessible growth surfaces.
- Growth geometry
- single-axis | branching | coalesced | irregular | unresolved Helps distinguish one formation from several merged formations and locate changes in growth direction.
- Basal attachment
- attached | partly detached | detached | obscured | unresolved Informs stability assessment and whether the original growth context survives.
- Mineral composition
- identified mineral phases, identification method and uncertainty Supports interpretation of deposition, alteration and suitable analytical methods without assuming composition from appearance.
- Drip-source relationship
- observed or inferred drip source, impact location, observation period and confidence Connects a growth surface to its water supply while allowing intermittent or shifting drips.
- Surface wetness
- dry | damp | wetted by observed drips | unresolved, with observation date Records present conditions without treating wetness as proof of mineral growth.
- Net surface change
- mm per stated interval, with method, uncertainty and detection limit Distinguishes measured accumulation or loss from an unsupported active-growth label.
- Growth-record continuity
- apparently continuous | interrupted | altered | unresolved, for a specified region Qualifies whether internal layers can support a chronological interpretation.
- Physical condition
- mapped fractures, missing material, surface alteration and contamination, with severity and evidence Supports protection decisions and comparison of condition over time.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 11 findings · 21 questions.
Identity and formation boundary Establishes why the object is a stalagmite and which material belongs to it.
An upward-growing deposit can be confused with neighbouring formations or lose its original context after breakage.
Formation evidence
Tests origin and growth direction rather than relying on outward shape.
Upward drip deposition
Records evidence that dripping water built the deposit upward from a supporting surface.
- What observations support upward mineral deposition from drips rather than a hanging deposit, flow coating or non-mineral lookalike? definition
- If the object is detached or overturned, what evidence establishes its original position and growth direction? provenance
Individual extent
Resolves boundaries at the base, neighbouring growths and overhead connections.
Merged and connected growth
Defines the individual where deposits merge or connect to another formation.
- Where does the stalagmite end and its substrate or surrounding flowstone begin, and which boundaries are obscured? boundary
- Do coalesced neighbours or a ceiling connection require linked formation identities, and what evidence supports that decision? boundary
Geometry and attachment Describes the growth form and its physical connection to the supporting surface.
Profile, axis changes and basal attachment affect recognition, interpretation and susceptibility to breakage.
External growth form
Locates the base, apex and changes in shape within a repeatable reference frame.
Profile and growth axes
Records dimensions and growth geometry without assigning an unverified cause to their variation.
- What are the height, widths at specified elevations and apex position relative to a documented base reference? measurement
- Where do growth axes divide or change direction, and can later observations reproduce these measurements? measurement
Support and fracture
Examines attachment and discontinuities relevant to physical integrity.
Basal and body integrity
Separates observed attachment and fractures from inferred stability.
- Which parts of the base are visibly attached, detached or concealed, and where are fractures or displaced sections? measurement
- Do observed fractures or attachment changes warrant restricting nearby activity or requesting specialist assessment? action
Drip supply and surface change Relates incoming water to current surface conditions and measured deposition or loss.
A dry visit does not establish permanent inactivity, and a wet surface does not establish growth.
Water delivery
Records the location, timing and variability of water reaching the formation.
Drip impact and variability
Connects observed drips to particular surfaces while retaining temporal uncertainty.
- Which drip sources reach the stalagmite, where do they strike, and are these relationships observed or inferred? provenance
- What drip intervals or water-delivery rates were observed, over what duration and under which seasonal conditions? measurement
Deposition and loss
Distinguishes wetness, mineral accumulation, dissolution and unresolved change.
Net growth evidence
Requires evidence and a timescale for any claim about current growth or surface loss.
- What repeat measurements demonstrate mineral accumulation or surface loss, and what is their detection limit? measurement
- What monitoring interval and method could resolve whether an apparently unchanged surface is growing, dissolving or stable? action
Mineral and growth record Characterises composition, layering and the limits of historical interpretation.
A stalagmite may preserve a growth history, but composition, interruptions and alteration constrain what that record supports.
Composition and alteration
Separates identified mineral phases from visual impressions and later changes.
Material identification
Records how composition was established and where alteration may affect interpretation.
- Which mineral phases are identified, by what method, and which parts of the formation do those results represent? provenance
- Where is there evidence of recrystallisation, dissolution, inclusions or surface coatings, and how confidently is it identified? measurement
Layering and chronology
Evaluates growth sequence and age evidence without assuming regular layer durations.
Record continuity and age
Relates observed layers and dated positions while preserving gaps and uncertainty.
- What evidence identifies growth layers, interruptions or erosional boundaries, and does any evidence establish their duration? measurement
- Which age determinations belong to which positions, and what uncertainties or material limitations constrain their interpretation? provenance
Conservation and research actions Connects condition and scientific value to permissible interventions.
Touching, installing equipment or removing material can affect both the growth surface and the retained research record.
Condition and exposure
Records damage and local activities that may affect the formation.
Damage and disturbance
Distinguishes documented change from uncertain damage origins.
- What breakage, abrasion, deposits or contamination are documented, and which earlier observations establish when they appeared? provenance
- Which nearby activities could contact the formation or alter its drip supply, and what protective measures are justified? action
Intervention selection
Evaluates observation, instrument placement and sampling against purpose and authority.
Justified access and sampling
Requires a specific objective, permission and assessment of material loss before intervention.
- Can the research question be answered through remote observation, existing measurements or previously collected material? action
- If contact, equipment installation or sampling is proposed, what authority permits it and what location, extent and effect on future growth or interpretation are acceptable? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
