Muzidian 2.8 Billion Years Old Land Core

Muzidian Old Land Core, located in Tianjingshan Village, Muzidian Town, Guifeng Mountains, covers an area of 200 square meters. It was the oldest ancient land nuclear material in Dabie Mountains 2.8 billion years ago. The rock body and the TTG Series in Biaoziao are known as the root of the Dabie Mountains. They are the keys to revealing the early evolution history of the earth and have important scientific research value. It belongs to the world-class important geological heritage protection point.

This outcrop, with an outcrop area of more than 5 x 10 square meters, is a remnant at the turning of the highway 1.5 kilometers east of Muzidian Town (southwest of the large outcrop area of Muzidian (Yan) Formation). The main lithology is amphibolite, amphibolite or pyroxene are found in the central part of the area, and epidote is common. The gneissic monzonitic granite of Shengli gneissic granite suite is extensively engulfed and migmatized intensely, forming banded and brecciary migmatites, and more granitic or feldspathic veins are interpenetrated, with a small amount of pyrite in the network fissures.

(Note: The paleocontinental core, in short, is the part of the earth's crust that has been stabilized and rarely deformed over a long geological period.)
