The type of rock that will be formed is METAMORPHIC ROCK.
Metamorphic rocks are pre-existing rocks that are formed as a result of physical or chemical alteration by mean of heat and pressure. The process transform the rock into a denser, more compact rock. Examples of metamorphic rocks are marble, gneiss and schist. Metamorphic rocks can be formed from already existing igneous or sedimentary rock. <span />
The data you will collect is the blood phenotype.By adding serums that each contains a particular antibody such as anti-A, anti-B, or anti-D ... to see if there's an agglutination with erythrocytes' antigen and the antibodies, proving the presence of the appropriate antigen in the blood.
This will help to confirm the blood grouping if this technique is done in parallel with the plasma test ( of Simonin-Michon).
