1. They are also classified as felsic or mafic, depending on the kinds and relative amounts of light and dark minerals.
2. Cumulate layering is very common in large mafic intrusions.
3. Alkali mafic subvolcanic body occurring in Bijiashan-Tongdongwan consists of clastic rock and lava.
4. The mafic granulite xenolith was first reported to have occurred in Early Mesozoic diorite in Harkin region, Eastern Inner Mongolia Autonomous Region, China.
5. Biotite is a subordinate constituent of the mafic and ultramafic rocks generally.
6. Late Precambrian mafic dyke swarms are extensively developed in the central North China Craton.
7. The Great Dyke of Zimbabwe is a layered mafic intrusion of igneous, metal-bearing rock that has been dated to approximately 2.5 billion years old.
7. Sentencedict.com try its best to collect and make good sentences.
8. Mafic intrusive rocks in Wuqiagou area, eastern part of Ahai Orogenic belt, include diorite porphyrite, olivine gabbro cumulates, and hornblende gabbro cumulates.
9. Granulite facies pelitic gneiss and mafic granulite outcropping in the Larsemann Hills, East Antarctica, underwent a complicated deformational metamorphic history.
10. Layered mafic intrusions are usually associated with economically important metals such as chromium, nickel, copper, platinum, titanium, iron, vanadium, and tin.
11. As to the activity of the components, the mafic component is more active than the felsic component.
12. Niobium-enriched arc basalts are mildly- to highly-alkalic mafic lavas that contain relatively higher amount of high field-strength elements (HFSE) than normal arc lavas.
13. The plutonic complex unit consists of gabbro, mafic cumulate and ultramafic cumulate. There exist complicated magmatic intrusive events in the plutonic complex and sheeted dike complex units.
14. The magma mingling between mafic magma and felsic magma is the primary mechanism responsible for the granitoids of crust-mantle mixed source.
15. Mafic granulites and amphibolites crop out in the Grove Mountains (GMs), 450km south of Zhongshan Station on the coast of Prydz Bay, East Antarctica.
16. The less dark rocks are dominated by biotite mica and amphibole, and darker, more mafic rocks by pyroxene and olivine.
17. The coastal area around Southeastern Fujian is located in the Changle-Nan'ao tectonic zone, where mafic dikes ( swarms ) were developed since late Mesozoic.
18. The Mesoproterozoic tectonic stress field could be simulated on the analysis of the distribution and mechanical origin of the Mesoproterozoic mafic dyke swarms in the central NCC.
19. Their geochemical characteristics of trace elements and Nd and Sr isotopes show that these mafic rocks erupted in a back-arc basin.
20. Based on the analysis of the ultra-long electromagnetic wave curves from Tanggu to Dalian, the geological body to effect the high gravity and magnetic anomalies could be a mafic intrusion.

22. Therefore, the magmas were the product of low partial melting of mafic eclogite at the base of the thickened crust, and their magma sources were affected by fluids.
23. The discriminant figures of tectonic setting show that the mafic rocks was formed in seamount setting.
24. The host rocks of the Mishuling intrusion consists of a grayish white porphyritic monzogranite-granodiorite-quartz diorite, in which mafic microgranular inclusions are well developed.
