Fluid Inclusions

Formation of fluid inclusions Fig 1-2

Fig. 2-12a: Sulfide with trapped fluid inclusion

Fig. 2-12c: Trapped organic matter in a small inclusion Fig. 2-12c: Trapped organic matter in a small inclusion. The quantity of organic matter makes it extremely unlikely that it precipitated from the trapped fluid. Rather, the inclusion formed around the organic matter.
