As showed by zinc SHRIMP chronometric age result of early Cambrian crystalline basememt in Luxi area, the forming age of Taishan group is in about 2750Ma. Tonalitic gneiss and belt type tonalitic gneiss with the age of 2.7Ga was formed in the first period of magmatic movement, TTG granites with the age of 2.6 Ga was formed in the second tectonic magmatic movement period, and medium basic rock-medium acid intrusive rock with the age of 2.55~2.5Ga were formed in the third tectonic magmatic period. From magma intrusion in mantle to large scale of kaligranite melting, large scale of crust were formed. A little of magma intruded along extensive crack which was formed by Archaean stiff crust cracking. According to rock property and age, early Cambrian intrusive rocks in Luxi area are classified again, and evolution history of early Cambrian crust in Luxi area is studied as well in this paper.
