A scanning tunneling microscope (STM) has been used to locally transform C60 molecules of a C60 fullerite thin film on Au(111) into a new amorphous form of carbon by application of a pressure in the GPa range. From the vertical tip movement during the transformation process, the local collapse of two monolayers of C60 is inferred. Based on atomically resolved STM images of this "collapsed fullerite" (CF) structure, a pair correlation function characteristic of an amorphous structure with a nearest-neighbor peak at 2.7 angstrom is presented here. The two-dimensional power spectrum of the real-space data exhibits no spots but rings, which are attributed to first and second nearest-neighbor distances of the CF structure. An analysis of the number of nearest-neighbors of each atomic feature shows that about 50% of the atoms have in-plane bonds to one other atom, and 40% have bonds to two other atoms.
