STRATIGRAPHY



Stratigraphy is the study of rock layers (strata) deposited in the earth. It is one of the most challenging of geologic subdisciplines, comparable to an exacting form of detective work, yet it is also one of the most important branches of study in the geologic sciences. Earth's history, quite literally, is written on the strata of its rocks, and from observing these layers, geologists have been able to form an idea of the various phases in that long history. Naturally, information is more readily discernible about the more recent phases, though even in studying these phases, it is possible to be misled by gaps in the rock record, known as unconformities.

Hi! I'm doing some research on Geologic Time and Earth's Layer but due to limited resources I can't find some journals regarding to the topic. I'm from Tacloban, Leyte Philippines where super typhoon Haiyan landed. Can you please tell me the important events in each period and all about the earth's layer and how are they being studied. Thank you in advance.
