Geology of Fujian : ウィキペディア英語版 | Geology of Fujian Fujian is a south eastern coastal province of China. The eastern half of the province is largely covered by Jurassic Period acid volcanic rocks and Cretaceous tuffaceous sandstone. However, there are rocks of a variety of ages including the oldest around 1800 Ma (million years old). The deposits from the Triassic are predominantly on land, whereas the older ones are marine sediments. Prior to the Ediacaran the continent was assembled from several terranes. In the early Paleozoic the environment was a continental slope. In the later Paleozoic the area was a platform, and from the Mesozoic period till now it has been affected by the edge of the Pacific Ocean. ==Stratigraphy== The Badu Group from the Lower Proterozoic consists of biotite schist and gneiss around 1800 Ma and is found noprth of Songxi. The Mayuan Group from middle Proterozoic consists of muscovite schist and includes leptite, marble and graphite beds.
