Writeup from MB 85:

Sologne

Centre, France

Fell 1860

Ordinary chondrite (H5)

A 54 g stone was found in 1992 by Yannick Dubouloz in a box in the attic of his late grandmother, who had lived in the town of Annecy, Haute-Savoie, France. In the box was a handwritten note saying that the stone was a meteorite that fell in Sologne in 1860. Mineralogy and classification (N. Dauphas and Y. Dubouloz, CRPG; B. Zanda, MNHNP): olivine, Fa19.4; pyroxene, Fs17.2; Co content of kamacite, 0.52 ± 0.02 wt%; shock stage S3; weathering grade, W1. See also Dauphas et al. (2000). Specimens: main mass, Y. Dubouloz; type specimen, 3 g, CRPG.

Sologne: discredited as an official meteorite name

Pierre-Marie Pelé, struck by the similarity of the grainy black crust of the meteorite “Sologne” with some Pultusk individuals, determined that “Sologne” is very likely a Pultusk sample. The first three lines of its old label (Fig. 1) probably actually read, “fragment d’aréolithe [sic] tombé en Pologne en 1868,” instead of what had long been interpreted to read, “fragment d’aréolithe [sic] tombé en Sologne en 1860”.  “Pologne” is French for “Poland”, and 1868 was the year of the Pultusk fall in that country.
The stone known as Sologne and those from the Pultusk fall are all H5 chondrites, with nearly indistinguishable silicate composition: Fa19.4±0.1 and Fs17.2±0.1 for olivine and low-Ca pyroxene in Sologne (Dauphas et al. 2000) vs. Fa19.3±0.5 and Fs16.9±0.4  in Pultusk (Krzersinska 2017). They are both shock stage S3 (Dauphas et al. 2000; Stöffler et al. 1991).

Sologne note
The name "Sologne" is now discredited as a distinct meteorite fall, and becomes a recognized synonym for Pultusk.
