| 摘 要： | 组成矽卡岩的矿物主要为钙铁榴石—钙铝榴石系列的石榴石和透辉石—钙铁辉石系列的单斜辉石,其矿物成分变化与红外光谱谱带的变化有明显的相关性,即石榴石的红外吸收谱带随着钙铁石榴石分子的增高,谱带向低频方向移动;单斜辉石的红外吸收谱带随着矿物含铁度的增高向高频方向移动。

| Abstract: | Skarn minerals consist mainly of garnets of andradite-grossu larite series, and clinopyroxenesof diopside-hedenbergite series. The changes of in composition of these minerals are apparently correlative with their respective infrared absorption bands. In andradite-grossularite series, the band shifts to low frequency side as andradite molecular increases due to the replacement of A18+ by Fe3+, while in minerals of dioposide-hedenbergite series, theFe (including (Mn) cations Fe will cause the band shifting to higher freqency.The rules described above are eompetent for garnets and clinopyrosenes of all kind of scarn ore deposits in identifying their chemcal composition and qeneration. |
