A limestone quarry in coarse-grained Precambrian marble.
Located about 2 miles NW of Oxford. This is another of Thomas Alva Edison's business ventures connected with his Portland Cement industry. The quarry was dormant for many years prior to the mid 1970's when it was worked by the Oxford Stone Co. who also operated a nearby quarry in gneiss.

In the 1980's the property was acquired by Millington Quarry Co. and turned into a major operation. Millington's holdings, along with those of many other aggregate producers in the region, were acquired by Tilcon in the 1990's. Tilcon is the current operator (2008).

The quarry is opened in the largest outcropping area of Precambrian marble south of the Franklin - Sterling Hill area 25 airline miles to the northeast. Proterozoic marble is best known in the Reading Prong Highlands in the Lime Crest and Franklin/Sterling Hill, NJ and northward to the Amity, NY area. However, marble outcrops sporadically along the northwest margin of the Reading Prong from its principal outcrop area southwestward into Pennsylvania. The marble exposed along the northwestern edge of the Reading Prong is now interpreted (Volkert, 2004) as a carbonate shelf on the margin of a back arc basin. The marble at Oxford is at least broadly equivalent to the Franklin marble in its type area. At Oxford the rock generally contains far fewer concentrations of silicate minerals. The spinel and corundum assemblages present at Lime Crest and elsewhere in the Franklin marble are very rare or absent at Oxford.
