滇西铁厂锡矿床矿石的矿相学研究
Study on Ore Microscopy of Tiechang Tin-Deposit in West Yunnan
【摘要】 根据矿床地质观察及矿石研究,矿床经历了两期六阶段的成矿过程.热液矿化期,成矿断裂多期活动,矿化多次叠加,以致在原生锡矿体中形成具有特色的脉动式逆向垂直分带.风化矿化期,使近地表含微细矿脉的蚀变碎裂混合花岗岩的锡石相对富集形成风化壳型锡矿.
【Abstract】 According to geological observation and are study,ore forming process can be divided into two epoches and six stages.During hydrothermal mineralization period,activities of mineralizing fault happened many tinies.and mineralization repeated time andagain.Therefore,pulsating contrary vertical zoning.which has its characteristics,eccurred in original tin oerebodies.During weathering mineralization period,cassiterites which occurred in cataclastic,aftered migmatitic granite containing tin ore veins were enriched relatively.Thus,weathering crust tin deposit was formed.
