辉长质斜长岩、橄长岩、微斑熔融角砾岩等岩屑和含钛玻屑中的辉石相对贫钙，主要为易变辉石(分别为En63 FS32 WO5，En66FS23WO11，En55FS38Wo7和En57FS35WO8)，而斜长岩质辉长岩和辉长岩岩屑中的辉石和晶屑辉石的成分变化比较大(分别为En31～33 FS35～48 WO19～34，En18～48 FS23～51 WO24～38+En1～9 FS65～86 WO14～26和En11～53 FS23～63WO6～36)，为易变辉石和普通辉石，以及少量三斜铁辉石。

The SDB eclogites, on the other hand, were strongly overprinted by a high-pressure granulite-facies metamorphism under conditions of p=1.9~2.0 GPa and T=873~948℃, followed by temperature and pressure decrease to the amphibolite-facies. The process of temperature increase with decreasing pressure from UHP eclogite to high-pressure granulite suggests that the SDB eclogites exhumed at low speed and underwent strong thermal relaxation at a level of crust-mantle transition or thickened lower crust.

都兰南带榴辉岩折返过程中经历了高压麻粒岩相变质的改造，高压麻粒岩阶段的p-T条件为p=1.9~2.0 GPa，T=873~948℃，并进一步经历了角闪岩相退化变质，说明都兰南带榴辉岩折返速率较慢，发生了壳幔过渡带层次的强烈热松弛。

At western segment of Altyn Tagh tectonic belt, The eclogites and khondalite series were recognized in Altyn Group (Early Proterozoic?) Which had been thought prviously that it consists of high greenschist facies and lower amphibolitic facies metamorphic rocks. They crop out at the northern slope and southern slope of Altyn Tagh Mountains respectively.

Based on structural features of karst rocks, the authors have divided the karst rocks of Huanglong Formation into four types, namely slightly corroded karst rock, medium degree corroded and porous karst rocks, strongly corroded brecciated karst rocks and strongly corroded and altered secondary gray-karst rocks.

石炭系黄龙组岩溶岩系是川东邻水-渝北地区天然气藏最重要的储层类型之一，依据岩溶岩的结构特征，将黄龙组岩溶岩系划分为弱溶蚀岩溶岩、中等溶蚀多孔状岩溶岩、强溶蚀角砾状岩溶岩和强溶蚀交代次生灰质岩溶岩等4种类型。

The lithological units of this province consist of brecciated mica-olivine pyroxenite pipe, olivine pyroxenite, pyroxenite, gabbro, basalt, diabase, alkali syenite and syenite dike, being dominated by basalt and diabase.

Comclusion: transpetrous presigmoid retrolabrinth approach was rational approach for surgery on petroclivus and -4- CPA; it抯 important for accomplish the surgery to study and master the anatomy and variance of this approach; there was relative anatomical relationship among those structure on posterior of petrous bone; AAMP was the extracranial mark of inflexion of TS and SS; LAM and PSC were obvious bone marks for operation; we can confirm the abraded range of petrous bone lean upon LAM and/or GSS beside abrading step by step as literature, and it抯 unnecessary and unrational to emphasize to show PSC if the surgical space was enough; preceding sigmoid sinus and high jugular bulb often appeared at right and would bring disadvantage effect; interspace ,between CN V and CNVII or CNVII and CNJXI, were available to reach clivus and manage the mass on the range.

经SS前迷路后入路是处理岩斜坡区、桥小脑角区病变理想的手术入路；研究和熟悉手术入路中的解剖结构及部分变异对指导手术十分必要；岩骨内测面的骨性结构之间有着相对稳定的空间关系；顶乳缝前角是SS和TS转接处在颅外的标志；IAM和PSC等结构可以作为手术中的重要骨性标志；以PSC确定岩骨的磨除范围是较安全和可靠的，但亦可以结合影像检查，以内耳道和乙状窦前缘为基点判定切除范围，如果操作空间足够，过分强调磨出半规管是不适当的；右侧GSS的宽度和深度较对侧大，SS前置和颈静脉球高位较对侧多见，这些都对右侧入路有不利的影响，但仍可以进行手术操作；三叉神经和面神经间隙及面l 神经和舌咽神经间隙方便到达斜坡并处理病变。l

The Sm-Nd isochron age (1182±50Ma) of Kangshan metamorphic complex has first been presented in the paper, which deny the tranditional point that the complex is Archean Taihua group. It's suggested that the plagioclase-amphibolite originates from subcon tinantal lithospheric mantal, assimilating and hybridizing minor crustal materials.

首次提供康山变质杂岩的Sm-Nd等时线年龄(1182±50Ma)，否定了康山变质杂岩是太华群的传统认识，并提出康山变质杂岩内斜长角闪岩原岩主要来源于大陆岩石圈地幔，同化混染了少量壳内物质。

The main characteristics of the skarn are as follows:(1)occurring as bedded,para-bedded in the contact zone between carbonate and microclastic rock,and its occurrence being accordance to the strata;(2)cut by later vein rock,so having no relation with the magmatic rock on genesis;(3)metasomatic skarn having replacement remnant texture,pseudobreccia structure,while depositional skarn,particulate crystall...

研究表明该夕卡岩的主要特征为：(1)呈层状、似层状赋存于碳酸盐岩和细碎屑岩接触带，产状与地层一致；(2 )被后期脉岩穿切，成因上与岩浆岩无关；(3)喷流交代夕卡岩具交代残余结构和假角砾状构造，而喷流沉积夕卡岩具微粒状结构、雏晶结构和层纹、条纹、条带状构造，反映了二者不同的喷流成因；(4)发育典型的低温夕卡岩矿物组合，其形成温度小于30 0℃；(5 )夕卡岩的稀土配分型式与围岩的一致。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
