Summary:
Candler Formation mapped as two separate lithologic units: phyllite and schist, and laminated metasiltstone. Phyllite and schist unit is described as medium- to dark-gray and greenish-gray mica phyllite and sandy laminated schist. Lenses and pods of feldspathic quartzite, metamorphosed quartzarenite, dolomitic marble, and dark-gray to medium-bluish-gray, laminated marble are common in upper part. Outcrop belt of phyllite and schists extends from the VA-NC boundary in Patrick Co., northeastward to at least the north end of Buffalo Ridge on the Amherst-Campbell Co. line. In Orange Co., the Candler includes the True Blue formation of Pavlides (1989, 1990). The laminated metasiltstone unit, found northeast of the Scottsville Mesozoic basin, is grayish-green, fine- to very fine grained, laminated schistose and phyllitic. In southeastern Albemarle Co., unit contains discontinuous interbeds of ferruginous metatuff. This unit conformably overlies the Catoctin Formation. Cambrian age shown here.
