单斜晶系角闪石族矿物是一类成分复杂、具有双链状结构矿物的总称。测试了宁镇地区的花岗闪长岩、矽卡岩和豫西地区的角闪片麻岩中的12个角闪石的穆斯堡尔谱,包括普通角闪石、阳起石和绿钙闪石,它们属Ca-角闪石类型。它们的晶体化学式为X_(2-3)Y_3Z_8O_(22)(OH)_2,阳离子在晶格中占有六种位置,但主要占据四个八面体M_1、M_2、M_3和M_4位:其中X阳离子Ca、Na、K、Mn为M_4或A占位;Y阳离子Mg、Fe~(2+)、Fe~(3+)、
Monoclinic amphibole minerals are a group of complex composition, with the double-strand structure of minerals in general. The Mossbauer spectra of 12 amphiboles from granodiorite, skarn and hornblende gneiss from the Ningzhen area were tested, including the common amphiboles, the actinolite and the green calcium Amphibole, they are Ca-amphibole type. Their crystallographic formulas are X_ (2-3) Y_3Z_8O_ (22) (OH) _2. The cations occupy six positions in the crystal lattice, but mainly occupy four octahedral M_1, M_2, M_3 and M_4 positions: in which X cation Ca , Na, K and Mn are occupied by M_4 or A; Y cation Mg, Fe ~ (2 +), Fe ~ (3+),
