Stop N: Hearst Tower Interior Lobby
214 North Tryon Street
This 47 story post modern office building (659 feet) was finished in 2002 and designed by architect: Smallwood, Reynolds, Stewart, Stewart & Associates, Inc. No photos are allowed inside the building for security reasons.
Located within the College Street lobby of the Hearst Tower, there are brass railings from the Au Bon Marche department store in Paris. These railings accentuate the tower’s art deco influences. The building lacks a 13th floor for superstitious reasons.
N1-N3: Floors and walls of the interior lobby
The lighter colored floor stone is an augen gneiss (N1 in Figure 44) with the trade
name “spray white” granite. Generally, augen gneiss is a high-grade metamorphic rock whose parent rock was likely granite. Augen comes from the German word for “eye”, as the sample’s main features are lenticular porphyroblasts of white plagioclase feldspars (1 in Figure 45). Black biotite compresses around these more resistant white feldspars in a
preferred orientation. The augen gneiss was quarried at Xiamen, China, near Beijing.
The second type of stone in the flooring is “dynasty black” granite. (N2 in Figure 44)
also from Xiamen, China. This granite is a very common countertop stone, which is
actually classified as a gabbro, an igneous rock with dark minerals.
The walls in the lobby are dominated by “Beijing white” marble (N3 in Figure 44)
from Yi Sin, China. This marble has distinctive stylolites (see stop D for a definition of stylolites) which are accentuated by a coating of insoluble residue. The marble was cut as facing pieces from the same block. When one of the pieces is rotated and they are placed
side-by-side, they create a “book-end” marble effect.
