Summary of Activities/Interests

Professor Neal's petrologic research uses a technique of crystal stratigraphy to explore lunar (mare) basalt and impact melt evolution. Crystal stratigraphy involves using quantitative petrography (in the form of crystal size distributions or CSDs) to evaluate the size distributions of different phases. This can identify different crystal populations that can give information on the samples' petrogenetic history. The CSDs guide the analytical phase of the investigation to different populations. Individual crystals are then analyzed by electron microprobe for major and minor elements, and by Laser Ablation ICP-MS for trace elements. Zoned crystals contain a wealth of information regarding sample history that the crystal stratigraphy approach can unlock.

Lunar Science Professor Neal's lunar research consists of two major thrusts: 1) Lunar Petrology; and 2) Lunar Geophysics.

1) Lunar Petrology: Research in this area is examination of melt rocks, both natural basalts and impact melts. Current projects include investigation of the petrogenesis of Apollo 12 and Apollo 17 mare basalts as well as the Apollo 14 and Apollo 16 impact melts, both using the crystal stratigraphy approach. Melt inclusions are also being analyzed to explore the petrogenesis of the Apollo 12 basalts.

2) Lunar Geophysics Professor Neal is the Principal Investigator on a proposal to NASA to send two landers to the lunar surface, each carrying a sophisticated geophysical instrument package. The science rationale for this mission is that we know very little about the interior of the moon, despite five seismometers being deployed on the lunar surface by Apollo; the small footprint of the Apollo network meant our knowledge of the deep interior would be limited. Each lander on the "Lunette" mission will contain a broad band and short period seismometer, two heat flow probes, an electromagnetic sounding experiment, and a laser retroreflector. The proposed mission is an international collaboration involving the USA, France, Germany, Japan, Switzerland, Austria, and Italy. The nominal mission will last four years.

Large Igneous Provinces (LIPs) : LIPs represent vast outpourings of lava at an unprecedented rate that is not known at present. Models have been constructed to explain such magmatic events that include a surfacing plume head, an upper mantle origin, and origin through meteorid impact. Distinguishing among these different hypotheses requires careful investigation. My research uses fieldwork and scientific ocean drilling to investigate the following oceanic LIPs: Kerguelen Plateau, Ontong Java Plateau, and the Hawaiian-Emperor Seamounts. One of the most important aspects of LIP origin is understanding the exact timing of formation. Do they form in one big pulse or several smaller ones? How long did this magmatism continue? A new avenue of research is to examine syn-LIP sediments to identify the onset and cessation of volcanism. [Photos 5, 8]

Mantle Petrology: Understanding the composition of and processes occurring in the mantle allow a much better understanding of how magmas are generated and how the mantle has evolved over time. Examinations of peridotite xenoliths and mantle-derived megacrysts are the targets for this research. An integrated approach to investigating mantle petrology involves major and trace elements in conjunction with isotope determinations. [Photos 2, 12, 13]


A Return to the Moon Is Crucial

June 16, 2016

It's not just a way station to Mars — it'sa way to build new industries. A return to the moon is crucial to the future of human space exploration — and not just for the experience it would give us in off-world living. Our satellite is also rich in resources ... A return to the moon could also inspire the next generation and advance technology just as Apollo did.

Momentum Builds for Creation of “Moon Villages”

January 6, 2016

Villages on the moon, constructed through cooperation between astronauts and robotic systems on the lunar surface, could become a reality as early as 2030. That’s the consensus of a recent international conference of scientists, engineers and industry experts, including Clive Neal, a University of Notre Dame planetary geologist.
