1997年降落在山东省鄄城县的陨石雨,是橄榄石-古铜辉石球粒陨石。该陨石中的金属矿物主要为铁纹石和陨硫铁,其次为镍纹石,金属矿物呈填隙状分布于以橄榄石和古铜辉石为主的硅酸盐矿物粒间及球粒周围。陨石中可见由铁纹石和镍纹石组成的显微蠕虫状连晶,是陨石中金属矿物在降温冷却过程中发生固溶体分离作用而成。陨石中金属矿物的分布特征表明,金属Fe-Ni和硫化物（FeS）应该是星云凝聚不同阶段的产物。陨石中金属矿物的成分和组构特征及陨石中出现的球粒结构、橄榄石的炉条结构等特征表明,该球粒陨石是星云物质快速冷却的产物。
1997年降落在山東省鄄城縣的隕石雨,是橄欖石-古銅輝石毬粒隕石。該隕石中的金屬礦物主要為鐵紋石和隕硫鐵,其次為鎳紋石,金屬礦物呈填隙狀分佈于以橄欖石和古銅輝石為主的硅痠鹽礦物粒間及毬粒週圍。隕石中可見由鐵紋石和鎳紋石組成的顯微蠕蟲狀連晶,是隕石中金屬礦物在降溫冷卻過程中髮生固溶體分離作用而成。隕石中金屬礦物的分佈特徵錶明,金屬Fe-Ni和硫化物（FeS）應該是星雲凝聚不同階段的產物。隕石中金屬礦物的成分和組構特徵及隕石中齣現的毬粒結構、橄欖石的爐條結構等特徵錶明,該毬粒隕石是星雲物質快速冷卻的產物。

Meteorites rain landed in Juancheng county of Shandong province are olivine - bronzite ehondrites. Metallic minerals in the meteorite are mainly kamacite and troilite, and accompanied by edmonsonite. Metallic mineralso were found in the interstitial olivine and bronzite -based intergranular silicate minerals and spherules around. Microscopic worm -like crystal stock composed of kamacite and troilite can be seen in meteorite. It is formed by separated function of solid solution of metallic minerals in the meteorite during the cooling period. As showed by distribution characteristics of metallic minerals, metal Fe - Ni and sulfide （FeS） are the products of different stages of nebular condensation. As showed by compositions and fabric characteristics of metallic minerals in meteorite, spherules structures in meteorites and grate structures characteristics, the chondrite is a product of rapid cooling of the nebula materials.
