| 1. | Gold and other heavy mineral placers are notable examples of lag deposits, but gravel and boulder bars are more common . 金和其它重矿沙虽是蚀余沉积物中值得注意的例子,然而卵石和顽石沙洲都是比较普遍的。 |
| 2. | Heavy mineral prospecting 重矿物勘探 |
| 3. | The heavy minerals in quaternary strata and its stratigraphic significance in luzhi , jiangsu province 苏州直第四纪重矿物地层及其意义 |
| 4. | The stratigraphy of heavy minerals and its significance in quaternary period , changzhou , jiangsu 江苏常州地区第四纪重矿物地层及其意义 |
| 5. | The sandstone contains lesser amount of heavy minerals such as zircon , garnet , tourmaline , and staurolite 砂岩中含少量的重矿物,如锆石、石榴石、电气石、十字石等。 |
| 6. | Beneath the relic sand of the outer shelf there is high grade of valuable heavy mineral sand ( for example ilmenite ) reaching the ii anomaly order of marine placers and it is of potential resource prospects 通过碎屑矿物判断,原岩应是中酸性岩浆岩和浅变质岩类。钛铁矿等有用矿物在细砂层位中出现较厚的砂矿异常,显示一定的浅海砂矿资源潜力。 |
| 7. | The contents of rare - earth element in coals are correlative to the contents of the ash of these coals , with a few of coal samples showing exceptional high contents of rare - earth element due to the presence of the heavy mineral assemblages 煤的稀土元素质量分数与灰分质量分数呈正相关关系,部分煤样品由于有富稀土元素的重矿物组合的存在而出现稀土元素的异常高值。 |
| 8. | According to the characters of the compositional heavy mineral , diameter and composition of gravel , primary sedimentary structure , the sediments came from east part of the basin . they had distinguishing feature of near provenance and quickly deposit 由朱巷组重矿物组合、砾径、砾石成分及原生沉积构造等特征反映出沉积物来自于盆地东部,并具有近源、快速沉积的特点。 |
| 9. | The magnetic susceptibility of dianchi lake modern sediment decreases progressively from the edge to the middle of the lake , distributes with the heavy mineral of sediment basically unanimous , increases along with the degree of depth , negatively correlates with the total phosphorus 滇池现代沉积物的磁化率大小由滨岸带向湖心依次递减,与滇池沉积物中的重矿物分布基本一致,在垂向上,随着深度的加深而变大,与总磷呈负相关关系。 |
| 10. | Under the hydrodynamitic condition in the outshelf heavy minerals are enriched to a certain extent . they are of horablede - epidote assemblage and contain some authigene ( pyrite and glauconite ) . the content of stable mineral is small and mineral maturity index ( trzg / hp ) is low 在外陆架水动力的作用下,重矿物有一定富集,重矿物以角闪石?绿帘石矿物组合为特征,含有一定量自生矿物(黄铁矿和海绿石) ,稳定矿物少,矿物成熟度低。 |
