Writeup from MB 110:

Northwest Africa 14298 (NWA 14298)

(Northwest Africa)

Purchased: March 2008

Classification: Enstatite chondrite (EL6)

History: Collected by nomads in Western Sahara and purchased by Romano Serra (OAM) at the Bologna Mineral Fair in March 2008.

Physical characteristics: A single piece weighing 163 g with no fusion crust.

Petrography: (V. Moggi Cecchi, L. Fabrizi, G. Pratesi, UniFi); The thin section texture consists of a fine-grained, pyroxene-dominant matrix, with minor plagioclase. No relic chondrules are visible. The main opaque phases are kamacite and troilite, partially weathered to iron oxides. Blades of alabandite and daubreelite are occasionally visible in troilite. The presence of alabandite, An content of plagioclase and Si content of kamacite point to a classification as EL chondrite;

Geochemistry: EMP (V. Moggi Cecchi, G. Pratesi, L. Fabrizi, UniFi) Orthopyroxene (Fs_2.5En_96.3Wo_1.2), plagioclase (An_13.7Or_3.8); Si in kamacite = 0.5 wt.%, Ti in troilite = 5.9 wt.%

Classification: Enstatite chondrite (EL6); S1; W3

Specimens: A total of 20.1 g specimen and one thin section are on deposit at MSN-FI (Inv.# RI3640). Museo del Cielo e della Terra holds the main mass.
