Geological Classification Of Stones. 311 Geological classification Based on their origin of formation stones are classified into three main groupsIgneous sedimentary and metamorphic rocks shown in Figure 1 1. According to their chemical compositionsilicious argillaceous and calcerous. Geological classification In this rocks are classified on the bases of formation These are of three types 1. Any unique combination of chemical composition mineralogy grain size texture or other distinguishing characteristics can describe a rock type.
Building stones are obtained from rocks occurring in nature and classified in three ways. There are three major types of rock. Granite marble and slate of meta morphic. Type of Stones Stones used for civil engineering works may be classified in the following three ways. Based on their origin of formation stones are classified into three main groups Igneous Rocks. Geologically the stones can be classified as follows.
Al though clay can hardly be classed with building stones it is not entirely out of place in this connection since it is employed in making.
On this basis rocks are classified as igneous sedimentary and metamorphic. Type of Stones Stones used for civil engineering works may be classified in the following three ways. Geological classification of stones. And sandstone limestone and clay of sedimentary. GEOLOGICAL CLASSIFICATION This is classification of rocks based on their origin and formation. 1 IGNEOUS ROCKS These rocks are formed by cooling and solidifying of the rock masses from their molten magmatic condition of the material of the earth.
