Ordinary chondrite, brecciated (L/LL5, S2)
Fell, 7 April 1990; 670 g

After a fireball was observed by several hundred people, a small stone fell onto a house and broke into fragments, the largest 135 g. The meteorite has two distinct brecciated lithologies — a dark lithology with olivine Fa31 and pyroxene Fs 25 composition, a light and more homogeneous lithology with olivine Fa26 and pyroxene Fs 21. Chondrules are somewhat more abundant in the lighter grey regions. In addition to the more or less expected kamacite, taenite, troilite and minor chromite, small amounts of albitic feldspar Cr-rich diopside, and glass are found. Lesser amounts of chlorapatite, ilmenite, and even copper are also reported.

Glanerbrug is one of the small group of 16 ordinary chondrites, including 3 witnessed falls, currently listed exactly as 'L/LL5' at the Meteoritical Bulletin Database [Nov 2015]. However, it should be noted that discussions still continue as to the proper exact classification for the meteorite. At least some of the discussion appears to be related to the fact that there is no clear consensus as to whether there is a separate original parent body (OPB) for L/LL chondrites in addition to the postulated OPBs of the L and LL chondrites.

The main mass has been kept at the National Museum in Leiden.
