岩石

Therefore, its UPb ages are likely to yield the age of metamorphic crystallization rather than resetting by simple diffusion, such that metamorphic titanite may preserve complicated UPb system that contains information of the whole metamorphic history of the rock, which can be revealed by in situ UPb dating, e.g., SHRIMP, LAMCICPMS and LAICPMS.

由于榍石的组成元素均为岩石中的主要元素，很容易与其它矿物、熔体及流体发生反应，所以榍石的U-Pb年龄记录的更可能是结晶年龄，而不是简单的扩散重置年龄；也因为它容易反应，变质榍石复杂的UPb体系可能记录了岩石的整个变质历史信息。

In contrast to zircon, titanite is quite reactive in most rocks contain Ca and Ti at different conditions. Therefore, its UPb ages are likely to yield the age of metamorphic crystallization rather than resetting by simple diffusion, such that metamorphic titanite may preserve complicated UPb system that contains information of the whole metamorphic history of the rock, which can be revealed by in situ UPb dating, e.g., SHRIMP, LAMCICPMS and LAICPMS.

Its stability may extend into eclogitefacies and highpressure granulitefacies in calcic rocks. Because of its high U in its structure and high closure temperature (upper limit of amphibolitefaces), titanite is an ideal UPb dating mineral.

它在岩浆岩中主要存在于高Ca/Al比值的岩石中，在变质岩中常见于绿片岩相、蓝片岩相和角闪岩相岩石，在钙质变质岩中其稳定范围可达榴辉岩相或高压麻粒岩相。

It contains a study of fluid flow in metamorphic environments and their interaction with rock properties such as porosity and tortuosity.

Field geological investigation, petrology and geochemistry study showed that three oil shale groups in Kazuo basin were developed in Member 1,2,3 of the Jiufotang Formation of Lower Cretaceous, the third oil shale group located in 3rd member have the greatest industrial significance. Oil shale always has the accompanying relationship with overlying sedimentary tuff or other tuffaceous strata.

野外地质调查和岩石学、地球化学研究表明：喀左盆地3个油页岩层群分别发育于下白垩统九佛堂组的一、二、三段，以位于三段的第三油页岩层群的工业意义最大；油页岩常与上覆沉凝灰岩或其它凝灰质岩石呈伴生关系。

The tuffaceous volcanic reservoir s of Xing'anling group in Hailaer Basin, Daqing Oilfield, includes andesite-rhyolite tuffaceous, andesite tuffaceous and trachy-rhyolite tuffaceous volcanic rocks.

针对这些特点，通过岩石水理特性实验和岩石力学特征研究，提出了以下解决措施：①凝灰质火山岩储层粘土含量高时，应提高压裂液的防膨胀性能，大排量施工，增加裂缝净压力；②碱性和偏碱性凝灰质储层，应研究使用低滤失压裂液，降低滤失量，同时提高压裂液的防膨胀性能；③凝灰质储层塑性较强时，应尽量提高施工排量。

The rock mass rating, rock mass classification and support systems proposed for fault zones in Tuzla tunnel are insufficient for explaining the deformation and failure mechanisms encountered in the tunnel.
