The holocrystalline porphyritic olivine basalts and pyroclastic rocks are the components of Pleistocene to recent volcanic activities.───的斑状斑状橄榄石玄武岩和火山碎屑岩是最近火山活动的更新世的组成部分。
scope is coeval with the spatial distribution of the Emeishan basalts.───整个剥蚀区的范围同峨眉山玄武岩分布区基本一致。
Isotopic systematics of flood basalts indicate that their sources are involved in crust-mantle mixing in a recycled mantle, decompression melting of lithosphere.───玄武岩的同位素体系特征表明它们的源区涉及再循环地幔的壳幔混合、岩石圈减压熔融、上—下地幔过渡带和似原始-略亏损的下地幔。
Oceanic basalts record the Earth's magnetic field as they solidify from molten lava symmetrically on each side of the mid oceanic ridges.───大洋玄武岩记录着地球磁场，因为玄武岩从熔融的熔岩固结时，在洋中脊的两侧是对称的。
Helium isotope compositions of the mantle-derived xenoliths and megacrysts from the Cenozoic basalts in Hannuoba were measured.───对该地区新生代玄武岩中幔源包体和高压巨晶的氦同位素进行了初步研究。
Discrimination of mechanism of formation of cenozoic basalts along shandong anhui part of tan lu fault zone by using rare earths.───郯庐断裂带鲁皖段新生代玄武岩形成机制的稀土判别。
The eruption of basalts in this period was tectonic ally controlled by the Yimu fault of the continental rifting type.───该时代的玄武岩浆喷出活动在构造上受到大陆裂谷型沂沐断裂带的控制。
Basalts come from the tipper mantle, a large quantity of olive xenoliths, arid the formation mechanism of partial melting of mantle.───玄武岩来源于上地幔，内有大量橄榄岩包体，其形成机制是上地幔部分熔融作用。
Ophiolites in west of the Namco Lake in Tibet are mainly composed of metamorphic peridotites, gabbro-diabases and basalts.───西藏纳木错西岸蛇绿岩主要由变质橄榄岩、辉长辉绿岩及玄武岩等组成。
Basalts are the rocks which are formed at mid-ocean ridges, and which make up the entire oceanic crust.
The Tianshan basalts may result from a mantle plume.
Alkaline basalts record the passage of the plateau over a hotspot during the Eocene.
But whereas the mare basalts are too dense to represent the lunar mantle, the highland rocks are not dense enough.
Basalts are examples of basic volcanic rocks, while andesites are intermediate between basic and acid.
Basalts are the dark lava rocks that fill mare basins.
The mare basalts are denser than the rocks which typify the highlands.
This suggests that the mare basalts and the highland rocks have both been derived from mantle rocks of intermediate density.
Mantle compositions that could yield both mare basalts and highland rocks are consistent with the constraints on the interior outlined earlier.
