Craton, Shield and Platform Explained in Geology
The Earth’s crust is made up of different geological structures that have formed over billions of years through complex processes like tectonic activity, erosion, and sedimentation. Among these structures, the terms craton, shield, and platform are used to describe the oldest and most stable parts of the continental crust. These structures play a crucial role […]
Porcellanite : composition, origin, uses and occurance
Poecellanite is a very fine-grained, hard and compact rock found in various part of the world. The rock range in colour from white and grey to brown and reddish depending on mineral composition and environmental conditions where it forms. Porcellanite is primarily composed of silica, clay minerals and varying amount of iron oxides and carbonates. […]
Earth’s inner core is changing it’s shape !
Recently, scientists have discovered that the shape of inner core of Earth has been changing over the past two decades. Earlier researchers have confirmed about slowing down of inner cores’s rotation and rotating in the opposite direction of the planet’s surface. The inner core of earth occurs as solid state and mainly composed of iron […]
Unconformity in geology & different types of unconformity
Definition An unconformity is a surface of erosion or non-deposition indicating a gap in geological record. It signifies a time break between two rock formations, indicating past geological events such as uplift, erosion, or changes in sedimentation rates. The strata lying above the unconformity are always younger than the strata lying below. The younger rocks […]
