Textural and compositional characteristics of metallic spherules in impact melt from Monturaqui crater, Chile

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 646-662, March 2025.
Abstract Samples of impactite from the small (~350 m diameter) Monturaqui crater in northern Chile contain Fe‐Ni metallic spherules sourced from the iron meteorite impactor. Textural characterization and quantification were done using SEM and μCT data. Two textural types are distinguished, with different size distributions.

Selective sampling of asteroids, the Moon, and Mars: Factors affecting the numerical abundances of members of meteorite groups

Meteoritics &Planetary Science, EarlyView.
Abstract Meteorite collection inventories show that many related meteorite groups have very different numerical abundances (e.g., lunar versus Martian meteorites; Eagle Station pallasites versus main‐group pallasites; eucrites versus diogenites; ungrouped Antarctic irons versus ungrouped non‐Antarctic irons; carbonaceous chondrite‐related (CC) iron ...

Antinomies of Alignment Redux: The United Arab Emirates and the United States

Middle East Policy, EarlyView.
Abstract Over the past three decades, the United Arab Emirates has forged a sturdy bilateral security alignment with the United States. It has also pursued foreign policies that conflict with US interests in the Gulf and the broader Middle East. This contradiction is usually attributed to a hedging strategy.

Middle Powers and Limited Balancing: Syria and the Post‐October 7 Wars

Middle East Policy, EarlyView.
Abstract This article contends that to explain the grand strategies of states in the Middle East, we must employ the concept of middle powers. Analyzing the case of Syria between 2011 and 2021, it finds that these actors preferred a strategy of limited balancing against direct threats to their national security.
