辽南庄河—凤城断裂构造变形及其成矿作用

ON THE PALEOENVIRONMENT AND THE CHANGE OF SEA LEVEL THROUGH THE CHARACTERISTICS OF SEDIMENTARY GEOCHEMISTRY —AS AN EXAMPLE OF MID LOWER CAMBRIAN SERIES IN THE EAST OF WEST SHANDONG PROVINCE

庄河－凤城断裂走向北东，形成于早中生代，属辽南区域性切壳断裂构造，规模大、变形强、活动期次多，对成岩成矿有重要控制作用。

The research on the Mid Lower Cambrian series in the east of West Shandong province indicates that δ 13 C and the δ 18 O and the geochemical characteristics of some elements,such as Sr,Ni,Ba,B not only show the sedimentary paleoclimite,paleosalinity,paleo water temperature and redox conditions,but also provide the evidence for defining the changing cycle of sea level and the expose interrupted planes.
