136 34 8 Eadu I H7· [)olQrnjtjc Sjlmone Facies LH7 consists oflhin- (0 n:edium-bcdOOl buff- to t.3n- .....eathering dolomitic siltstone which is massive to ripple cToss-laminated (plale 3.19). This facies is only e"posed in the Rocky Harbour area (Gonzatez-Booorino. 1990) and in Western Brook Pond. It is associale
IJ7 themselves brecciated, and angular (plate 3.20). The thickness of this horizon is about 15m. Both subfacies arc interpreted as olistostromes. and the elUent of imernaldeformation within both subfacies probably places each of them within facies class F2.2 (dislocated, brecciated and balled strata). Subfacies a) is predominantly a deformation of unlithified Cow Head lithologies. wllereas subfacies b) is completely intrclformationallo the wilier Head Formalion. Neither of the above subfacies were recognised by Gonzalez-BonaTina (1990). 14 iO Other Charactcrj$ljg and local Inlemr!;tatjQD$ An almost ubiquitous characteristic of the lower pan of the lower Head Formation is a zone of deformation of shale associated with injection of sandstone dykes and sills (plale 3.21). This lone. which was referred toby Botsford (1988) as the 'slump and injeclion facies', is of variable thickness, bUI ~:an extend up to 60 m above the base of the formation. Sandstone dykes and sills are present in the sections at Western Brook I'ond, and slumping associated with the formation of olistostromes is present al Martin Point Nonh. Both slumping and injeclion features are present near the base of the Lower Head Formation in the Bay of Islands area (Botsford, 1988). and sandslOne dykes are presenl al the base of the formation in the Rocky Harbour area. Hiscolt (1979) has noted simrlar features at the base of the Tourelle Formation in Quebec, and has related their preseoce to Ihe existence of impermeable shale in the section which aCled as a seal and promoted liquefaction and intrusion of sands.
