保山在真緬地槽之南西端,其造山运动与喜馬拉雅褶皺时期相当。本区受燕山运动的影响,形成今保山構造盆地;沉積了新第三纪的瀉湖相沉積。(注:僅根据鑽孔的资料还未遇到老第三纪地層)作者在保山盆地一百平方公里的面積內,作了地質踏查工作,蒐集了有关新地質构造运动的一些証据,闡述如下,僅供参考。但作者对新地質構造这門科学学習很差,野外实际经验不足,不免有错誤之处,敬希批評指正。 (一)礦床成因类型不会表示新地質構造运动:保山××砂礦为瀉湖相新第三纪礦体,后期被季節性的流水及河流
Baoshan is located in the southwestern tip of the Burma Trench, and its orogeny is comparable to that of the Himalayan fold. Affected by the Yanshan movement in this area, the present Baoshan structural basin is formed; the Neoproterozoic lacustrine sediments were deposited. (Note: The author has not encountered the Old Tertiary formation only based on the borehole data.) The author made a geotechnical survey in an area of 100 square kilometers in the Baoshan Basin and collected some evidence about the new geotectonic movement. Set out below, for reference only. However, the author of the new geological structure of this poor science study, lack of field practical experience, can not help but have mistakes, King hope criticism correction. (I) The genesis type of the deposit will not indicate the new geotectonic movement. The Baoshan × × sandstone is the Neogene Tertiary ore body in the lagoon and later is covered by the seasonal flow and the river
