Lunarcrete Wikipedia

David Bennett, of the British Cement Association, argues that lunarcrete has the following advantages as a construction material for lunar bases: Lunarcrete production would require less energy than lunar production of steel, aluminium, or brick. It is unaffected by temperature variations of +120 °C to −150 °C.

Chibougamau Independent Mines

The Lac Dore Complex (LDC) is a stratiform, layered intrusive complex composed principally of metaanorthosite with lesser amount of metagabbro to anorthositic gabbro and is host to many of the copper/gold deposits of the Camp. The anorthosite represents 70% to 90% (by volume) of the lithologies present within the LDC.

Mar 28, 2019· Anorthosite is a mineral in the plagioclase series of aluminium silicates with varying content of calcium and sodium. In the chlorination process, calcium and sodium will be chlorinated first and will remain in the charge as solids. Aluminium is then chlorinated to AlCl 3, which is gaseous at temperatures above 180°C. Corresponding processes can be used for other feldspar minerals.

Dec 23, 2014· In contrast, spinels produced in experiments involving anorthosite and green glass magma produced spinels (green circles) with lower Mg# and slightly lower Cr# than those in pink spinel anorthosite. Overall, the experiments suggest that reaction between magnesian suite magma and anorthosite is a reasonable mechanism for producing pink spinel anorthosites.
