Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
System context
Rockis part ofCrustEstablished
rock is part of crust.
Mechanism: Earth's crust is made of rock, so the whole rock cycle plays out within it.
- Wikipedia (English & German editions) verifiedmoderate evidence
Hydrocarbon reservoiris part ofRockEstablished
Hydrocarbon reservoir is a part of rock.
Mechanism: A hydrocarbon reservoir is a body of porous, permeable rock that traps oil and gas.
Igneous rockis aRockEstablished
igneous rock is a kind of rock.
Mechanism: Igneous rock is rock formed when molten magma or lava cools and crystallises — one of the three great rock families.

Marbleis aRockEstablished
Marble is a kind of rock.
Mechanism: Marble is a metamorphic rock formed from recrystallised limestone.
Metamorphic rockis aRockEstablished
metamorphic rock is a kind of rock.
Mechanism: Metamorphic rock is rock transformed by heat and pressure deep in the crust, which recrystallises existing rock without fully melting it.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Removing this node severs the only sampled structural route between Hydrocarbon reservoir and Oil reservoir — a non-redundant bridge here.
structural · Structural removal simulation — not a historical or causal counterfactual.
Currently dark in the atlas: no key date stored · 12 of 12 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Structural neighbourhood: 12 → 37 → 169 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- Non-redundant bridge — removing it severs a sampled route between neighbouring clusters. structural
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Mineral, Isotope geochemistry, Crust and Sedimentary rock.
Through this lens it connects to Mineral, Crust, Sedimentary rock and Igneous rock.
