COMPREHENSIVE ANALYSIS ON THE MAGNETIC FABRIC OF LISHUI VOLCANIC ROCKS

HE SHAO-YING;TANG ZHEN;XU TONG-CHUN (East China Bureau of Petroleum,MGMR,Nanjing 210031) (Second Geological Survey Party, Bureau of Geology and Mineral Resources of Jiangsu Province, Liyang 213300) (Institute of Geophysics, State Seismological Bureau, Be  
The magnetic properties of Cenozoic-Mesozoic volcanics in Lishui is introdued. According to the varying degrees in differentiation and cluster of tile directional distribution of three AMS principal axes for each site, five categories can be grouped.It is considered that the density of rocks concering the AMS categries and could be referred to as a simple distinguishing parameter for them of the products of a cycle of volcano.Combining with geophysical prospecting,the state of volcanic vent and the extension of tuff can be deduced.The estimate of flow direction for lava with maximum or minimum susceptibility direction is applied there.
