Diverse, well-foliated, multiply-deformed, variably foliated, metasedimentary and metavolcanic rocks closely associated with the Border Ranges Fault System. Sedimentary protoliths were shale, chert, tuffaceous arenite, and limestone; volcanic protoliths were probably mostly basalt (Winkler, 1992). Consists of thinly layered and complexly folded quartz-mica schist, greenschist, crossite-epidote schist (blueschist), and epidote amphibolite (Connelly and Moore, 1979). Whereas metamorphism varies from greenschist to amphibolite facies (Winkler, 1992), locally glaucophane-bearing and crossite-bearing rocks suggest unit was metamorphosed under conditions transitional to and including blueschist facies (Forbes and Lanphere, 1973; Carden and Decker, 1977; Carden and others, 1977; Connelly and Moore, 1979; Winkler and others, 1981; Bradley and others, 1999). Outcrops along northern flank of Chugach Mountains in Anchorage, Seldovia, and Valdez quadrangles are closely associated with Border Ranges Fault System and the McHugh Complex. Unit is also exposed along the west side of Afognak, Shuyak and Kodiak Islands, associated with the Border Ranges Fault System and the Uyak Complex. Includes the schist of Liberty Creek of Winkler and others (1981; Richter and others, 2006), the Knik River schist of Winkler, 1992 (also called the Knik River terrane of Pavlis, 1983; Pavlis and others, 1988), the Seldovia Schist of Roeske (1986; see also Cowan and Boss, 1978; Bradley and others, 1999), and the Raspberry Schist of Roeske and others (1989). Raspberry Schist of Roeske and others (1989) was subdivided into two units that consist of (1) metabasite and metasedimentary rocks that have some relict textures and phases preserved, including pillow shapes and bedding and (2) a unit that is completely recrystallized and preserves no original textures or phases. Carden and others (1977) reported 10 K/Ar ages on mica, chlorite, and amphibole from unit that range from 196.6±5.8 to 157.8.3±4.8 Ma, and Bradley and Karl (2000) reported 40Ar/39Ar plateau ages on mica of 191.7±0.3 and 190.98±0.3 Ma and on hornblende of 191.92±0.6 Ma. Roeske and others (1989) reported Rb/Sr isochron ages ranging from 212 to 189 Ma. Dating of the blueschist facies metamorphism of this metamorphic complex supports a pattern of decreasing age from west to east, as originally suggested by Sisson and Onstott (1986); however, it is unlikely that the reported ages are a true reflection of the timing of metamorphism. Clark (1972, cited in Winkler, 1992) reported a single Permian fossil collection from limestone. Winkler (1992) suggested that the diverse protolith lithologies may indicate tectonic mixing prior to metamorphism
