Explanation:
Serpentine
- Formation: it forms through serpentinization, a geological low-temperature metamorphic process where low-silica mafic and ultramafic rocks are oxidized and hydrolyzed with water into serpentinite.
- Characteristics: rich in magnesium and water, light to dark green, greasy-looking and slippery feeling. It can resist the transfer of heat. A source of asbestos, architectural stone, ornamental stone, gem material
- Minerals present: it follows the formula (X)2-3(Y)2O5(OH)4 where X can be magnesium, iron, nickel, aluminum, zinc, or manganese; and, Y will be silicon, aluminum, or iron.
Green Schist
- Formation: they form by regional metamorphism of mafic igneous rocks through depth of burial, and proximity to batholiths.
- Characteristics: The green is due to abundant green chlorite
- Minerals present: actinolite and epidote mainly, but they can also include quartz, orthoclase, talc, carbonate minerals, and amphibole.
Basalt Pillow
- Formation: it forms when lava of basaltic compositions erupted underwater. The rapid cooling of the lava forms the pillow-shaped bodies.
- Characteristics: they are volcanic igneous rocks, very dark, almost black color.
- Minerals present: Basalt has a lower percentage of silica and a higher percentage of iron and magnesium than other volcanic rocks.
Umber
- Formation: it develops in Cyprus massive sulfide deposits.
- Characteristics: is not one precise color, but a range of different colors, from medium to dark, from yellowish to reddish to grayish depending on the iron oxide and manganese in the clay
- Minerals present: contains iron oxide and manganese oxide and sulfide precipitates like pyrite.

The country that shares the island of Hispaniola with Haiti, is the Dominican Republic.
Here's a map I had to draw for a project to show the location on Haiti and the Dominican Republic.
I hope this helps!
