And apatite. by these analyses and comparison with general granite both in china and the world and with the granite in other au or cu belt in china, the characteristics of the granite in this area are concluded as follows. it belongs to magnetite - i or syntectic granite and has crust - mantle mixed characteristics ; it was formed mainly by crystallization differentiation of melting magma and multiphase varied intrusion ; the degree of differentiation evolvement is not high ; the granite and its enclaves p. re congenetic ; the range of temperature is about 500 - 700, the range of pressure is about 2. 50 gpa - 4. 35 gpa, and the range of oxygen fugacity ( lg fo2 ) is - 15. 53 - - 14. 00 ; most granite bodies formed before the collision of plates, and few formed after the collision of plates
通過對測試數據的分析與綜合研究,並同中國和世界一般花崗巖類以及中國主要金、銅成礦巖體的花崗巖類進行對比,得出本區花崗巖類巖石具有以下特徵:屬
磁鐵礦-型或同熔型花崗巖,其巖漿物質具
殼幔混源特徵:主要由熔融態巖漿經結晶分異作用,通過多期變速上侵而形成;其分異演化程度較低;寄主巖基和包體具有同源性;巖石的形成溫度范圍約為500 - 700 ,壓力大約為2 . 50gpa - 4 . 35gpa ,氧逸度值1gfo _ 2為- 15 . 53 ? 14 . 00 ;該巖帶主要形成於板塊碰撞前消減的活動板塊邊緣期,為燕山至喜馬拉雅早期的大陸邊緣火山弧環境的產物。

Hollow ferrites particles are the alternative to conventional solid ferrites particles, which have lower density, larger specific surface area and stability. moreover, it is expected electromagnetic wave can be reflected and absorbed again and again in the cavum of hollow particles which become its black hole. in addition, their electromagnetic parameters can be adjusted in a certain range by changing the thickness of the shell and the diameter of hollow microspheres, and the ability of absorbing microwave can be expected to improve
