It could be divided into six paleogeotemperature evolution stages from early cretaceous to recent based on the result of apatite fission - tracks analysis ; subsidence - buried history analysis shows that chagan experienced fault depression stage during early cretaceous bayingebi - suhongtu period , transional stage from fault depression to sag in yingen period , and sag stage since wulansuhai stage 磷灰石裂变径迹模拟分析结果认为早白垩世至今大致可分为6个古地温演化阶段；沉降?埋藏史模拟揭示查干凹陷经历了早白垩世巴音戈壁?苏红图期的断陷期、银根期的断?坳陷转化期和晚白垩世乌兰苏海期以来的坳陷期。
The formation process of green loose stone , be called an outside to living to pour to filter on the geology because of , matching these conditional rocks is the volcano of the acidity jet of rock with contain rich mineral apatite of granite , be matching these conditions to become on the earth green loose the mineral of stone is rare scarcity , is a very precious rare jewelry 绿松石的形成过程,地质上称为外生淋滤成因,符合这些条件的岩石是酸性的火山喷出的岩和含富矿物磷灰石的花岗岩,在地球上,符合这些条件成为绿松石的矿物罕见稀少,是很珍贵的稀有珍宝
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 通过对测试数据的分析与综合研究，并同中国和世界一般花岗岩类以及中国主要金、铜成矿岩体的花岗岩类进行对比，得出本区花岗岩类岩石具有以下特征：属磁铁矿-型或同熔型花岗岩，其岩浆物质具壳幔混源特征：主要由熔融态岩浆经结晶分异作用，通过多期变速上侵而形成；其分异演化程度较低；寄主岩基和包体具有同源性；岩石的形成温度范围约为500 - 700 ，压力大约为2 . 50gpa - 4 . 35gpa ，氧逸度值1gfo _ 2为- 15 . 53 ? 14 . 00 ；该岩带主要形成于板块碰撞前消减的活动板块边缘期，为燕山至喜马拉雅早期的大陆边缘火山弧环境的产物。
In this paper , the researches on the substitutions of ca - polyhedral , p - tetrahedral and channel positions in apatite structure are reviewed , the structural sites , substitution forms and mechanism of isomorphic ions are discussed , and the influence of the substitution of this mineral upon the environmental mineralogy is briefly described 摘要综述了作为重要环境矿物材料的磷灰石在钙位、四面体位和结构通道位置上类质同象替换的研究进展，讨论了替换离子的结构占位、替换形式和机理，并就替换对这种矿物在环境治理领域应用的影响进行了简要评述。
Oxide films with different thickness and properties can be anodically formed on the surface of ti6a14v alloy under different electrochemical conditions . the bonding strength of bonelike apatite layer formed on the titanium oxide films to the substrates under different heat treatment temperature is examined under tensile stress 本文研究了钛及钛合金植入材料在不同的电化学、化学处理条件下生物活性薄膜的制备、生物活性骨质磷灰石的形成过程及机理以及不同热处理温度对表面磷灰石与试样基体结合强度的影响。
This preliminary research focus on the tectonic uplift in late mesozoic - early cenozoic after the main collision oregeny to understand more and detail on the total process of tectonics evolvement in east dabie mountain and beihuaiyuan area . the research works that have been done are : apatite fission track dating , apatite thermal - evolvement patterns ; the fluid characteristics including fluid inclusions " microthermometer , the compositions , 5 d - 8 18o , and their geochemistry , thermodynamics parameters 为更全面了解东大别山及北淮阳地区大地构造完整的演化，并为之提供研究实例积累，本研究主要从热年代学及造山后流体特点角度对东大别山及北淮阳构造区碰撞造山后中生代未-新生代初构造隆升活动进行了初步探讨。
