目前各队在片麻岩中发现小规模鞍山式铁矿很多,而土法炼铁中,寻找富矿是当务之急。 我们检查了许多鞍山式铁矿露头,他们多半呈捕虏体形状出现于花岗岩——花岗片麻岩中,这些花岗岩一般对矿铁富集是否有影响?目前所得到资料是不多的。我队在大辛庄北,蔡店黑山子检查矿点时遇到鞍山式铁矿与花岗岩接触处品位变富的现象,对此问题可能提供一些线索。
At present, each team found a lot of small-scale Anshan-type iron mines in the gneiss, while in indigenous iron-smelting, looking for rich ore is a top priority. We examined a number of Anshan-type iron outcrops, most of them in the form of xenoliths in granite-granite gneiss, these granites generally have no effect on the enrichment of iron ore? The current information available is scarce. My team in Daxinzhuang North, Cai shop Montenegro check mine met Anshan-type iron ore and granite contact at the phenomenon of enrichment, the issue may provide some clues.
