“green” and“ ancient” is its main feature, so we try our best to keep these characters in this plan .

《Book of Changes》and the great thinkers of the pre-Qin period emphasize the ancient and contemporary significances.

The Dongbake gneissic tonalite in northern Kangxiwar,West Kunlun,is a suite of intrusive rocks disintegrated for the first time from the Paleoproterozoic Ailiankate Group-complex in four 1:250000 sheets such as Kangxiwar and Chalukou sheets.

The SHRIMP age data and geochemical results of the Palaeoarchaean dioritic gneiss and fine-grained trondhjemite of the ancient Dongshan rock belt from the Anshan area are reported in this paper.

The Palaeoproterozoic Erdaowa Group distributed in the north Hohhot, Nei Mongol is composed of metamorphic detrital sediment and carbonate with intermidiate basic volcanics.

The rhyolites in the Upper Luliang Group of Shanxi Province of China are Palaeoproterozoic A-type volcanic rocks.

Palaeoproterozoic formation lacks variety of standard fossils, thus it become difficult to compare the whole world formations or large .
