ENGINEERING PREPARASI fossil FORAMINIFERA

Technical preparasi fossil Preparasi fossil foraminifera small / micro foram Preparasi fossil foraminifera large / macro foram

A. Preparasi small fossil foraminifera The process of rock disintegration The process of washing rock The process pengayakan The process of separation of fossil

1. The process of decomposition Stone ditumbuk sediments with a mallet until the fractional-linear fraction of the middle between 3 - 6 mm Soaked in the solution H2O2 (hydrogen peroxide) to a pulp.

2. rock washing process Rock sample to be washed with clean water After the clean fossil are dried in the oven

3. Pengayakan Process After the fossil in the oven and then in diayak sieve size 30 mesh or 50 mesh

4. The process of separation of fossil Fossil planktonik separated by type and bentonik using the microscope

Tools and Materials Tools: Glass trophy Palu wood Microscope Sieve Botol sampel - Bottle sample Tray

Material: Sample matrix berfosil H2O2 Detergent
