Two-phase fluid inclusions in carbonaceous chondrite calcite crystals, viewed in transmitted light. (a) Probable primary fluid inclusion in the Murray CM2 chondrite at lower magnification (red circle). (b) Same inclusion in Murray at higher magnification. (c) Probable primary fluid inclusion in the Tagish Lake C2 chondrite at lower magnification (red circle). (d) Same inclusion in Tagish Lake at higher magnification. (e) Probable secondary fluid inclusions along a healed fracture in the Tagish Lake C2 chondrite. (f) Probable primary fluid inclusion in Ivuna at lower magnification (red circle). (g) Same inclusion in Ivuna at higher magnification. (Online version in colour.)
