Lodranites are a small group of primitive achondrite meteorites that consists of meteoric iron and silicate minerals. Olivine and pyroxene make up most of the silicate minerals. Like all primitive achondrites lodranites share similarities with chondrites and achondrites. [1]

2019年12月1日 · GRV 020043 suggests a range of peak temperatures on the acapulcoite-lodranite parent body similar to that of ordinary chondrites, but shifted to higher temperatures, perhaps consistent with earlier accretion.

2018年5月1日 · In this work, we review the properties of the acapulcoite-lodranite clan, including a comprehensive review of individual members, and the insights they provide into the process of asteroid differentiation and partial melting.

In this context, the acapulcoite–lodranite meteorite clan (ALC), which represents the products of thermal metamorphism and low-degree partial melting of a primitive asteroid, is an attractive target to study the processes of early planetary differentiation.

Using a suite of 10 samples of the acapulcoite–lodranite clan (ALC), we have developed new correlations between spectral parameters and mafic mineral compositions for partially melted asteroids. A well-defined relationship exists between Band II …

2025年1月1日 · Primitive achondrites, including ureilites, brachinites, acapulcoites, lodranites and winonaites represent a transitional type of meteorites between chondrites and achondrites (Prinz et al., 1983). The PAs have different thermal evolution history than chondrites, although their compositions are similar to chondrites (Prinz et al., 1983).

2014年6月3日 · Here, we use 2-D and 3-D finite-difference numerical models to determine the formation time, initial radius of the parent body of the acapulcoite-lodranite meteorites, and their formation depth inside the body by applying available geochronological, thermal, and textural constraints to our numerical data.

History: A single stone of 91 g was bought in Rissani, Morocco, in 2001. Physical characteristics: It is oblong shaped, ~5 cm in length, and ~2 cm in diameter. The fusion crust is altered and reddish dark brown. Discrete regmaglypts are visible. One side is broken, altered, and covered with desert varnish.

Lodranites can be described as chondrites that were heated to the point where FeNi and FeS reach an eutectic point. At this point partial melting occurred ...
