Use this geological calculation for a transparent first-pass interpretation of measured rock, soil, fluid, well, stratigraphic, isotopic, geophysical, or seismic data under an explicitly selected model.

Clinoform height (m)

Vertical clinoform height (shelf-edge to basin-floor relief) in metres.

Foreset dip

Foreset dip in degrees.

Along-slope length of a clinoform surface from its vertical relief and foreset dip: L = h / sin(dip). The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Slope length (m)

Along-slope length of the clinoform surface in metres.

• Stratal terminations and systems tracts are interpretations sensitive to seismic resolution, datum, compaction, subsidence, sediment supply, chronology, and depositional model. A geometric angle or thickness alone does not identify sequence boundaries.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Compare independent measurements and models, retain units and analytical metadata, propagate uncertainty, and validate interpretations against logs, cores, maps, laboratory data, or field observations.

• Clinoform Height Calculator

  Vertical relief of a clinoform from its along-slope length and foreset dip: h = L * sin(dip).

• Fault Throw Calculator

  Vertical component of net dip slip on a fault plane: throw = dip slip * sin(dip).

• Stratigraphic Thickness True Vs Apparent Calculator

  For a bed cropped out over width w perpendicular to strike on horizontal ground: true thickness t = w sin(delta) and vertical (apparent) thickness t_v = w tan(delta), with dip delta in degrees.
