The genesis of calcite and dolomite carbonatite
When calcite sinks into a region rich in earlier precipitated calcite, this creates disequilibrium crystallization of dolomite and produces calcite–dolomite assemblages. Once the peritectic is bypassed, either in equilibrium or disequilibrium conditions, dolomite is the sole carbonate crystallizing and will lead to the formation of …

setFill() / Reference / Processing
The setFill() method defines the fill color of a PShape.This method is used after shapes are created or when a shape is defined explicitly (e.g. createShape(RECT, 20, 20, 80, 80)) as shown in the above example.When a shape is created with beginShape() and endShape(), its attributes may be changed with fill() and stroke() within beginShape() and endShape().
LA-ICP-MS U-Pb carbonate geochronology: strategies, progress, and
Results of in situ U–Pb dating of calcite spherulites, cone-in-cone (CIC) calcite and calcite fibres from a calcareous concretion of the upper Ediacaran of Finnmark, Arctic Norway, are reported. Calcite spherulites from the innermost layers of the concretion yielded a lower intercept age of 563 ± 70 Ma, which, although imprecise, is within ...
