In contrast, the less abundant HT and LT2 basalts may imply a weakening of the influence of the mantle plume activity.

相反，厚度较小的HT和LT2玄武岩则可能是意味着地幔柱活动影响的减弱。

The Cenozoic basalts in mainland of eastern China are the products of multiple extrusion.

本文以中国东部6个地区的新生代大陆玄武岩及其幔源包体为研究对象，测试和搜集了玄武岩的常量元素、微量元素和单斜辉石斑晶的化学成分及Sr、Nd同位素资料以及幔源包体的常量元素、微量元素和矿物化学成分。

Answering these problems will play an important role not only in the study of the Emeishan basalts and the mantle_plume interaction, but also in the investigation of their relation to mineralization.

The low values of Nb/U (7~8) suggest that the basalts probably experienced the addition of some subduction-related materials and/or a certain degree of crust contamination.

较低的Nb/U比值(7~8)暗示该玄武质岩浆在形成过程中遭受了一定程度的大陆地壳混染或与俯冲过程有关的物质的加入。

We examined the origin and source of both high-Ti and low-Ti basalts of most large igneous provinces on Earth and found that they are generated from distinct mantle sources, rather than time-dependent.

根据对地球上两类玄武岩的源区和成因研究，发现它们应该是来自不同的地幔源区，而与其形成的时间没有关系。

REE abundances and Sr and Nd isotopic composition in mantle xenoliths from basalts in Hannuoba are reported in this paper.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
