The Dharwar Craton: Geological Significance, Structure, and Economic Importance

Leave a Comment / Geology EN, news /

The Indian shield consists of five major Archean Cratons: Dharwar, Bastar, Singhbhum, Bundelkhand, and Aravalli. The Indian shield, comprising the Precambrian basement, is primarily made up of granitic gneisses and migmatites, known as the Peninsular Gneiss or Fundamental Gneiss. The Peninsular Gneiss was emplaced on an older Greenstone belt, a relic of the Primordial Crust,

Chronostratigraphy Introduction Lithology (Lithostratigraphy): The stratigraphic units described in the preceding lectures are rock units distinguished by: Magnetic characteristics Fossil content (Biostratigraphy) Seismic reflection characteristics To interpret Earth’s history, stratigraphic units must be related to geologic time. The ages of rock units must be known. Chronostratigraphy: Establishing the time relationship among rock units is called

What are the principles of biostratigraphy?

Leave a Comment / Geology EN, news /

The characterization and correlation of rock units on the basis of their fossil content is called biostratigraphy. It is fundamentally different from a lithostratigraphic unit that is defined by the lithological properties of the rock. The concept of biostratigraphy is based on the principle that organisms have undergone successive changes throughout geologic time. Thus, any
