1. Epidote may be quite conspicuous.

2. The processing flowsheet of "epidote removal by magnetic separation-calcite and quartz removal by flotation" is selected.

3. The eclogites are composed of garnet, phengite, epidote, quartz, rutile, etc.

4. Epidote is one of the water-bearing minerals which can keep stable during peak ultra-high pressure ( UHP) metamorphism.

5. The bright green epidote in the center can also be gray, brown, or nearly black.

6. Kinds of heavy minerals, magnetite, amphibole, epidote, limonite and so account for 81% and have their presence in all stations.

7. The result showed that dominant minerals were amphibole group, epidote group, schistose minerals, authigenous pyrite and metallic minerals.

8. The wall rock alteration near the ore body is very thin, and mainly represents as the skarnization, which made the garnet, epidote, hedenbergite , tremolite etc.

9. The major mineral association in keratophyre rocks from Donggouba area is actinolite + chlorite + epidote + pumpellyite + albite.
