出溶铬铁矿的三种结构类型。A型晶粒由富Al的主体组成，其含有富Fe客体的气泡和罕见的较小薄片; B型晶粒具有富Fe的主体，其含有富Al客体的气泡和致密的薄片网络; C型晶粒含有非常精细的富Al和富Fe薄片的共生体。尖晶石棱柱体中的混溶隙呈隧道状，从Fe 3 O 4 -FeAl 2 O 4 -FeCr 2 O 4面延伸到MgFe 2 O 4 -MgAl 2 O 4 -MgCr 2 O 4面。如果出溶作用开始于或接近熊牙山东部区域变质作用的峰值温度，则不混合的温度接近600摄氏度。修改期刊摘要。
Three textural types of exsolved chromites. Type A grains consist of an Al-rich host that contains blebs and rare smaller lamellae of an Fe-rich guest; type B grains have an Fe-rich host that contains blebs and dense networks of lamellae of an Al-rich guest; type C grains contain a very fine intergrowth of Al- and Fe-rich lamellae. Miscibility gap in the spinel prism is tunnel-shaped and extends from the Fe 3 O 4 -FeAl 2 O 4 -FeCr 2 O 4 face to the MgFe 2 O 4 -MgAl 2 O 4 -MgCr 2 O 4 face. If exsolution began at or near the peak temperature of regional metamorphism in the eastern Beartooth Mountains, the temperature of unmixing was near 600 degrees C.--Modified journal abstract.
