I1: Walls (I1 in Figure 29) contain “Calacatta Gold Marble” building stone from Italy.
This is a fine-grained, white to beige marble, formed from carbonates deposited as part of
the Lias group of the early Jurassic Period (~180 - 200 million years ago).
I2: Flooring (I2 in Figure 29) is composed of “Botachino Fiorito Marble” building stone.
This light beige, magnesian limestone is also of the Lias group of the Jurassic Period.
While this stone is called a ‘marble’ in the US and Chinese markets, in Europe it must be
called a magnesian limestone, according to the “European Standard” of building stones.
I3: Flooring (I3 in Figure 29) is composed of “Ruoms Limestone”. This dark, fossiliferous limestone is from Ruoms, a city in southern France.
I4: Flooring (I4 in Figure 29) is composed of a light-gray, coarse-grained granite building
stone known as “Luna Pearl” from either Italy or Brazil.
I5: Flooring (I5 in Figure 29) is composed of dark-colored gabbroic anorthosite. This
stone is known as “Black Galaxy Granite”. Black Galaxy is quarried near Ongole,
Andhra Pradesh, southern India. The gold specks are due to the presence of magnesium-rich orthopyroxene (“bronzite”). Black Galaxy is one of the more common stones used
throughout the US for countertops in kitchens and bathrooms.
I6: Flooring on second level.
It is worth the trip up the escalator to view the nice examples of bisectional coiled
ammonoid fossils in carbonate rocks (Figure 30). It is located in the floor tile just to the
right of the top of the up escalator.
