对“康滇地轴”轴成矿环境的初步探讨

A PRELIMINARY DISCUSSION ON THE ENVIRONMENT OF URANIUM METALLOGENIESIS IN KANGDIAN AXIS

本文是根据“康滇地轴”的地壳演化历史和铀的地球化学特性来探讨“康滇地轴”的铀成矿环境,认为“康滇地轴”既有有利于铀成矿的地质环境和条件,又有不利的因素,因此,应加强基础地质研究,以各种成矿理论为指导选择有利地段,对“康滇地轴”进行第2轮找矿。

According to the history of the crustal evolution of Kangdian (WestSichuan-Yunnan)axis and uranium geochemical features, this paper makes adiscussion on the environment of uranium metallogenesis in Kangdian axis.It is suggested that there are some advantageous geological environments andgood conditions as well as soine disadvantageous factors for uranium depo-sit. So the second phase of uranium exploration in kangdian axis mustbase on strengthening investigation on basic geology and choosing thefavourable section by various metallogenetic theories about uranium deposit.
