New Technique which reveals about how continents were formed

I heard a recent news about the scientists who have developed a new technique which reveals them how the continents which were formed initially. The new technique which allows them to know how the rare minerals evolved from the ancient rocks. This will help them in determining the formation of earth's continent billion years ago. By analyzing the composition of minerals, scientists can predict the date of formation of ancient volcano rocks.

By aligning the formation of similar rocks which have same age and composition scientists could determine the early land masses which were clubbed together. In a Geological survey, it explains much of the geology which exists today were formed around 300 million years ago when the super continent pangea existed. By analyzing the rocks which formed when the continent shifted can help in reconstruction of land masses which existed early.

Scientists too discovered that molten magma, which prevails in the center of the earth filled the cracks formed during the shift of the continents. The magma cools down as years pass by to form a veins of basalt - a volcano rock, which has magnetic composition reveals about the rock formation. By combining these rocks formed in a volcano scientists could determine the age. Some of the ages could not be determined still because their formation had different composition of minerals. Now-a-days with the help of new techniques, scientists can recover minerals such as baddeleylite.
