Proportions of Exposed Igneous, Metamorphic, and ...

Abstract. Of the rocks exposed on the Earth's surface, 66 percent (±3.5 percent) are sedimentary and 34 percent are crystalline, at the 95 percent confidence level. Extrusive igneous rocks average about one-fourth of all crystalline rock outcrops, with the highest percentages in Asia and South America. Less than 5 percent of all Precambrian rocks ...

Sedimentary Rocks Article about Sedimentary Rocks by The ... Sedimentary rocks constitute about 10 percent of the earth’s crust by volume but cover 75 percent of the earth’s surface. Most of the rocks are concentrated on continents (500 million cu km) and continental slopes (190 million cu km); the ocean floor accounts for 250 million cu km.

SEDIMENTARY ROCK CHARACTERISTICS Geologyfans

2021-4-19  Figure 1 – Composition of sedimentary rocks in relation to the percentages of the main components. The 3D geometry of most sedimentary rock units can vary from tabular (Figure 2a), lenticular (Figure 2b), and wedge shaped (Figure 2c) to sinuous, all of which are largely dependent on the environment of deposition, although erosion and faulting will in some circumstances modify their shapes.

Sedimentary rock types: relative proportions as a function of geological time. Garrels RM, Mackenzie FT. Proportions of sedimentary rock types remaining today differ from period to period. These differences may be chiefly the result of differential rates of deposition and erosion of the various components of the rocks.

It all depends on what the geologist wants to do with them.

carbonate sedimentary rocks - CHC

The most common carbonate sedimentary rocks are limestone and dolostone, but also Sodium and Potassium Carbonates are common. Limestone is a sedimentary rock composed mainly of calcium carbonate (CaCO3), usually calcite, sometimes aragonite. As well it may contain considerable amounts of magnesium carbonate (dolomite).
