Little is known about how stony corals build their calcareous skeletons. There are two prevailing hypotheses: that it a physicochemically dominated process and biologically mediated one. Using combination of ultrahigh-resolution three-dimensional imaging two-dimensional solid-state nuclear magnetic resonance (NMR) spectroscopy, we show mineral deposition driven. Randomly arranged, amorphous nanoparticles initially deposited in microenvironments enriched organic material; they then aggregate...
The Moon contains chlorine that is isotopically unlike of any other body yet studied in the Solar System, an observation has been interpreted to support traditional models formation a nominally hydrogen-free ("dry") Moon. We have analyzed abundances and isotopic compositions Cl H lunar mare basalts, find little evidence anhydrous lava outgassing was important generating isotope anomalies, because (37)Cl/(35)Cl ratios are not related abundance, or D/H manner consistent with lava-outgassing...

It includes 10 falls (Arpu Kuilpu, Djadjarm, Glendale, Kindberg, Madura Cave, Motopi Pan, Orconuma, Punggur, Tihigrin, Winchcombe), with 2014 ordinary chondrites (including 1 ungrouped chondrite), 220 carbonaceous 11 ungrouped), 212 HED achondrites, 69 lunar meteorites, 62 ureilites, 43 iron 35 Martian 31 Rumuruti chondrites, 27 primitive 24 mesosiderites, 19 relict (all...

Abstract During the six Apollo missions, astronauts collected 2196 lunar samples, nearly all of which have been studied over past five decades. Six samples remained unexamined until 2019 and were saved to be analyzed by next generation scientists using advanced modern laboratory facilities. Now more than 50 years after Apollo, NASA is returning Moon with Artemis will return geologic from a different region surface Apollo. Curation play an instrumental role in helping prepare for safe these...
Abstract– Knowledge of Martian igneous basaltic compositions is crucial for constraining mantle evolution, including early differentiation and convection. Primitive magmas provide direct information about their source regions, but most meteorites either contain cumulate olivine or crystallized from fractionated melts. The recently discovered meteorite Northwest Africa (NWA) 5789 an olivine‐phyric shergottite. NWA has special significance among the because it appears to represent one...

[1] A new lunar rock type, rich in (Mg, Fe)Al spinel and lacking abundant olivine pyroxene, was recently detected by near-infrared reflectance spectroscopy the M3 instrument on Chandrayaan-1 spacecraft. No such material has been described from rocks, either returned samples or meteorites. Here we describe a fragment of containing ∼30% meteorite ALHA 81005. Although is not identical to (it contains ∼20% + pyroxene), both share defining feature an unusual enrichment spinel. The fragment, 350 ×...
Abstract– Northwest Africa (NWA) 1068 is one of the few olivine‐phyric shergottites (e.g., NWA 1068, Larkman Nunatak [LAR] 06319, and Roberts Massif [RBT] 04262) that not depleted in light rare earth elements (LREE). Its REE pattern similar to basaltic shergottite Shergotty, suggesting a possible connection between shergottites. To test this link, we have investigated high‐pressure near‐liquidus phase equilibria for meteorite bulk composition. Our results show composition does represent an...
Abstract Knowledge of Martian igneous and mantle compositions is crucial for understanding Mars' evolution, including early differentiation, convection, the chemical alteration at surface. Primitive magmas provide most direct information about their source regions, but meteorites either contain cumulate olivine or crystallized from fractionated melts. The new meteorite Northwest Africa ( NWA ) 6234 an olivine‐phyric shergottite. Its magnesian cores (Fo 78 are in Mg‐Fe equilibrium with a...
In the last decade, it has been recognized that Moon contains significant proportions of volatile elements (H, F, Cl), and they are transported through lunar crust across its surface. Here, we document a segment cycle in granulite breccia 79215: impactinduced remobilization volatiles, vapor-phase transport with extreme elemental fractionation. 79215 ∼1% volume fluorapatite, Ca5(PO4)3(F,Cl,OH), crystals to 1 mm long, which is reflected analyzed abundances Cl, P. The apatite molar F/Cl ratio...
Abstract Previous estimates of the volatile contents Martian basalts, and hence their source regions, ranged from nearly volatile‐free through similar to those found in terrestrial subduction zones. Here, we use bulk chemistry meteorites, along with apatite amphibole chemistry, constrain interior. Our show that content region for meteorites is Mid‐Ocean‐Ridge Mantle source. Chlorine enriched compared depleted mantle but region; fluorine primitive mantle; water consistent mantle. results...
Abstract The petrogenetic models of the lunar crust are built on returned Apollo and Luna samples collected from limited parts nearside that chemically unusual (i.e., material rich in K, Rare Earth Elements, P [KREEP]) not representative entire lithologic suite. Mg‐suite is part this sample collection ubiquitously has geochemical characteristics indicating involvement KREEP their petrogenesis seemed to be linked Procellarum Terrain (PKT). However, it unclear if necessary for magmatism or...

Abstract The double drive tube 73001/2 is a regolith core and was collected on the Light Mantle at Station 3 during Apollo 17 mission. This preserves an in situ record of space weathering compositional stratigraphy, providing insights to thickness local reworking time scale. We measured dissection passes 2–3 73002 1–3 73001 using high‐spatial resolution multispectral imaging system, analyzed products individual soil grains from pass 2 transmission electron microscopy analysis. Our results...
Abstract Large terrestrial impacts may produce vast subsurface hydrothermal systems, capable of generating conditions favorable to the origin life. Modeling suggests that these systems persist for >1 million years basin‐sized craters; however, direct experimental constraints on system duration are needed. Paleomagnetism be used as a tool study nature and postimpact generated within upper peak ring 200 km diameter Chicxulub crater (Yucatán Peninsula, México). Previous work observed suevite...
Abstract The Mars Exploration Rovers (MER) Spirit and Opportunity , sent to Gusev crater Meridiani Planum, respectively, determined the chemical composition of martian materials with their Alpha Particle X‐ray Spectrometers (APXS). MER APXS was effective at routinely quantifying major, minor, select (Ni, Zn, Br) trace elements levels down ∼50 ppm but often reached detection limits for other (e.g., Ga Ge during typical individual analyses a single sample). To enable precise quantification...

The nearly identical chemical compositions, even though their host formed at different places on Moon. These granulites distinct from other materials unique...
Abstract— The newly found meteorite Northwest Africa 6234 (NWA 6234) is an olivine (ol)‐phyric shergottite that thought, based on texture and mineralogy, to be paired with Martian meteorites NWA 2990, 5960, 6710. We report bulk‐rock major‐ trace‐element abundances (including Li), of highly siderophile elements, Re‐Os isotope systematics, oxygen ratios, the lithium ratio for 6234. classified as a shergottite, its bulk composition, element abundance Fe/Mn, Al/Ti, Na/Al.
