Data
| 1 Main lith | 2 Comment |
|---|---|
| Shocked target rocks | |
| Granitoid | Coarse-grained, granitic, or syenitic rock. |
| Granitoid-pegmatite | Ultracoarse-grained, granitic, or syenitic rock. |
| Granitoid-aplite | Fine-grained, granitic, or syenitic rock. |
| Felsite | Fine-grained intrusive felsic rock. |
| Dacite | Porphyritic rock with phenocrysts of plagioclase feldspar, quartz, and alkali feldspar in a groundmass of plagioclase and mafic minerals. |
| Diabase/dolerite | Medium-grained mafic rock contains pyroxene crystals visible to the naked eye, <2 mm. |
| Porphyritic diabase/dolerite | Medium-grained, porphyritic mafic rock contains plagioclase feldspar laths visible to the naked eye, ~2 mm or greater, and pyroxene crystals visible to the naked eye, <2 mm. |
| Monomict breccia | |
| Granitoid | Authigenic breccia with clastic matrix of granitoid composition (see above). |
| Polymict breccia | |
| Lithic impact breccia | Polymict impact breccia with clastic matrix containing shocked and unshocked mineral and lithic clasts but lacking cogenetic melt particles. |
| Suevite | Polymict impact breccia with particulate matrix containing lithic and mineral clasts in all stages of shock metamorphism, including cogenetic impact melt particles, which are in a glassy or crystallized state. |
| Impact melt rock | Crystalline, semihyaline, or hyaline rock solidified from impact melt containing variable amounts of clastic debris of different degrees of shock metamorphism. |
| Clast rich | >25% clasts. |
| Clast poor | 0%-25% clasts. |
| Clast free | 0% clasts. |
