成岩

The ages of 42 to 48 Ma may be mixing ages. Finally the origin of zircons and rock － controlling mechanism are discussed.

最后对锆石的成因和花岗岩的成岩机制等进行了初步探讨。

A perfume made from the oil of this plant .

一种分布很广的成岩长石。

0The temperature of thermal evolution of black shale series is of a great significance in expoundingrock-forming and ore-forming condition.

热演化温度是成岩成矿的重要因素。

P species, main as Ca-P and organic P forms, showing rego〓 pollution and karst area of lake watershed, inorganic P〓 related to Ca〓, Al〓, Fe〓 content in the overlying water, sediments is not a simple reservoir of dissolved phosphate and particle phosphate, near the interface, near 98% of total P existed as active forms, they may release to overlying water through reduction dissolution, deadsorption in the period of early diagenesis, only 2% of P as fixed forms, which mainly remained in the sediments, sediment was an important resource of nutrients of ovrelying water.

高原湖泊沉积物中的磷以有机磷和Ca-P形式存在为主，反映了高原湖泊流域污染和碳酸盐地区的整体背景，无机磷形式与水体吸附体Ca〓，Al〓和Fe〓的含量有关。底部沉积物不是溶解性磷酸盐和颗粒磷酸盐的长期储存场所，几乎有98%的磷是活性的形态存在，它们通过早期成岩作用在还原条件下还原，溶解和释放又重新回到上覆水体，只有2%的磷以固〓态的形式稳定保存于沉积物中，因此，沉积物为水体营养程度的重要来源。

The results indicate that the diagenetic types are various and the reservoir experienced intensive compaction, intensive cementation, complicate alternation and polyphasic solution.

结果表明，十屋断陷深部断陷层的成岩作用类型较全，经历了强烈的压实作用和胶结作用、复杂的交代作用和多期次的溶解作用。

When peats developed to lignites through diagenesis,95.1%-99.9%of their original iodine was lost.

当泥炭经过成岩作用形成褐煤时其本身含有的碘逸失率为95.1%～99.9%。

A widely distributed rock-forming ''.

一种分布很广的成岩长石。

This paper presents a method for evaluating the vertical seal of disparate faults using the section pressure, content and plastic strength of fault gouge and the quantity of later rock-forming fill.

提出了利用断面压力、断层泥的含量和塑性强度、后期成岩程度综合判定不同性质断层垂向封闭性评价方法。

Content and plastic strength of fault gouge and the quantity of later rock-forming fill. For example, the vertical seal of the F1 fault of Kela 2 structure in Kuqa depression was evaluated according to this method.

提出了利用断面压力、断层泥的含量和塑性强度、后期成岩程度综合判定不同性质断层垂向封闭性评价方法。

Tectonic action is the main force causing fractures in the area; diagenesis influences, in a way, the generation and developmental degrees of fractures.

构造作用是本区裂缝形成的主要动力，成岩作用对裂缝的生成及发育程度有一定的影响。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
