查询词典 basalts

The central peaks of several craters on the flanks of Syrtis Major are made up of an even more silica-rich rock, granite, that may have formed by extreme crystal separation or by large-scale remelting of earlier basalts.

在大三角侧面，几个火山口的中间尖点是由一种矽含量更高的岩石──花岗岩所构成，可能是经极度晶体分化，或早期玄武岩大范围重新熔融而形成。

The Permian volcanic rocks from Jianshui area tectonically intruded into southwest part of Shizong-Mile fault belt. It is mainly comprised of basalts, basaltic andesites, andesites and a little picrites.

滇东南建水地区二叠纪火山岩构造侵位于师宗－弥勒断裂带的西南段，以玄武岩、玄武安山岩和安山岩为主，夹有少量苦橄岩。

Some characteristic ratios suggest the picrites and ankaramites were derived from asthenospheric mantle, and high Os/Ir ratios reflect the involvements of pelagic sediments. Pd/Ir versus Ni/Cu diagram implies that the picrites and ankaramites were not primary magmas, but MgO-high basalts with excess olivines, whereas Pd versus Cu diagram suggests a S-undersaturated primary magma.

一些铂族元素的特征比值指示了苦橄岩和富辉玄武岩起源于软流圈地幔，而高的w/w比值则暗示了源区中有深海沉积物的加入。w/w-w/w图解说明本区的苦橄岩不是原始岩浆，而是原始的高镁玄武岩中有过剩橄榄石的加入，而w-w图解则说明原始岩浆硫不饱和。

The Middle Devonian Beitashan Formation consists of a series of intermediate-basic volcanic rocks intercalated with more than 100 m thick picritic layer at the bottom, whereas the Middle Devonian Yundukala Fm. is composed of a series of shallow-sea fine-clastic rocks interbedded intermediate rocks and intermediate-basic rocks. The Late Devonian Jiangzierkuduke Fm. includes pyroclastic rocks intercalated with intermediate-basic and intermediate-acid rocks, whereas the Late Carboniferous Batamayineishan Fm. consists chiefly of basalts and basaltic andesites intercalated with tuff, siltstone and carbonaceous shale.

其中中泥盆世北塔山组为一套中基性火山岩，并且底部含有厚度超过100m的苦橄岩；中泥盆世蕴都喀拉组为一套浅海相细碎屑沉积岩夹中性、中基性火山岩；晚泥盆世江孜尔库都克组为火山碎屑岩夹中基性和中酸性火山岩组合；而晚石炭世巴塔玛依内山组以玄武岩和玄武安山岩为主，夹凝灰岩、粉砂岩和炭质页岩。

Basalts recovered from the Siqueiros transform exhibit a wide compositional range from primitive to evolved compositions.

东太平洋洋隆Siqueiros转换断层带(西经103°～104°、北纬8°20′～8°30′)，位于中美洲之西可可斯板块与太平洋板块交接处(图1)。

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。
