Lodranite

Lodranites are a small group of

The lodranite group is named after Lodhran, Pakistan, where the type specimen fell on 1 October 1868 at 14:00.^[2] Eyewitnesses of the fall reported a loud bang accompanied by a rising dust cloud to the east of the city, which led to the discovery and retrieval of the meteorite.^[3][4] The "meteorite from Lodran" was first described by Gustav Tschermak in 1870.^[3] He described the meteorite being "apart from the nickel-iron it is an olivine-bronzite aggregates of such outstanding sort, that has never been found in a meteorite before only similar to the terrestrial olivine rock". George Thurland Prior was the first to classify the lodran meteorite as the only member of the lodranite group. He also saw close similarities to the ureilites.^[5]

Description

Lodranites are primitive achondrites. They are coarser grained than

The Lodran meteorite is described as having roughly equal amounts of metal, olivine and pyroxene which make up most of the volume. Other minerals include sulphide, chromite, phosphide and chrome-diopside.^[7]

Parent body

The lodranites and acapulcoites share the same parent body which was probably similar to an S-type asteroid. The lodranites are coarser grained and yield higher temperatures with isotopic methods and are therefore thought to be from greater depths within the parent body.^[2]

The cooling path of the parent body can be reconstructed by using
