Although these features are well-developed in hydrated carbonaceous chondrites and some micrometeorites, their formation mechanism remains poorly understood. This study provides new insights into the understanding of physical vesiculation processes by presenting the results of vesicle size distribution (VSD)\u2014i.e., a quantitative method for vesicle analysis\u2014applied to the study of the Tagish Lake (C2-ung) meteorite fusion crust. Tagish Lake was chosen because it shows a scoriaceous texture and a significant number of vesicles (about 24,000 vesicles\/mm2), thus allowing statistical analysis. Vesicles range from being spherical to irregular-shaped and from a few m to ~70 m (equivalent diameter) in size. Vesicle size distribution and cumulative number density analyses show a high nucleation event and a fractal distribution of the vesicle population, respectively. We suggest these features are due to disequilibrium degassing processes, which simultaneously produce continuous\/accelerating vesicle nucleation and growth. Finally, possible analogies between the scoriaceous Tagish Lake fusion crust and the space-weathered \u201cfrothy layer\u201d on the surface of Ryugu\u2019s grains could be found in terms of vesicularity. &#8220;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Xhonatan Shehaj, Stefano Caporali, Ernesto Palomba and Giovanni Pratesi Minerals 2024, 14(1), 99 LINK (OPEN ACCESS)PDF (DOWNLOAD) &#8220;Vesicles are characteristic structures within the outer layer of many stony meteorites\u2019 fusion crusts.
