Lunar Igneous Intrusions

Shallow Magmatic Intrusions in the Lunar Nearside Highlands?

2755. [19] Wieczorek, M. A. et al. (2013) Science 339, 671-675. Figure 1: Locations of floor-fractured craters [2] plotted on a basemap of crustal thickness [19]. Floor-fractured craters are preferentially located in regions of intermediate (20-30 km) crustal thickness. Mare deposits are located primarily on the lunar nearside and in regions of thinner crust.

Ancient igneous intrusions and early expansion of the Moon revealed by GRAIL gravity gradiometry.

The earliest history of the Moon is poorly preserved in the surface geologic record due to the high flux of impactors, but aspects of that history may be preserved in subsurface structures. Application of gravity gradiometry to observations by the Gravity Recovery and Interior Laboratory (GRAIL) mission results in the identification of a population of linear gravity anomalies with lengths of hu...

The Search for Water in Igneous Lunar Materials: a Re-assessment of the Lunar Magmatic Volatile Budget

Introduction: Magmatic volatiles such as H 2 O, F, Cl, CO 2 , and S play a critical role in physiochemical processes that control thermal stabilities of minerals and melts, magma eruptive processes, and transport of economically important metals. Of these volatiles, water is the dominant magmatic volatile in terrestrial magmas both because of its abundance and its strong effect on physical prop...
