Lunar and meteoritic palaeomagnetism: common origin contested (reply)

Chemical individuality of lunar, meteoritic, and terrestrial silicate rocks.

A Post Accretionary Origin for Meteoritic and Cometary Organic Solids?

Introduction: The insoluble organic matter (IOM) contained with in all chondritic meteorites constitutes a significant reservoir of extraterrestrial organic matter that in some cases may be as high as 3.5 wt. % [1]. Whereas considerable effort has been made to develop a molecular understanding of meteoritic IOM, there remains considerable uncertainty regarding its origins, i.e., was IOM formed ...

ON ORIGIN OF Xe-HL IN METEORITIC NANODIAMONDS

Xenon in the Presolar Diamonds: The finest grains of nanodiamonds identified in the carbonaceous and nonequilibrium ordinary chondrites are the most abundant relic grains, for which, as well as for the silicon carbide and graphite, the presolar origin is assumed [1].They could be apparently formed by condensation in cool stellar atmospheres or in the extreme PT-conditions of reprocessing the ma...

On the nature of Guinier-Preston zones in meteoritic and lunar orthopyroxene

Introduction: Upon cooling in their host rocks, orthopyroxenes undergo cation ordering and exsolution processes. The state of order achieved during cooling [1] and the type and morphology of the exsolution products depend on the rate of cooling. Often, the formation of stable exsolution phases is preceded by the formation of metastable phases, e.g. Guinier-Preston (GP) zones. GP zones consist o...

Origin of glass deposits in lunar craters.

country to the economic activity existing in developed countries. Incidentally, my planning office has just finished a feasibility study for an area in the Amazon Basin where 500 families may be settled in 14,400 hectares (1 hectare = 10,000 square meters), with a loan of $16,000 (United States dollars) per family extending over a 10-year period. After 10 years each family will have paid the lo...
