“…Conversely, living forms such as the annelid worms Titahia and Torlessia (= Terebellina), described as "the most distinctive fossils of the Torlesse" by Fleming (1970), have never been found in the Murihiku, apart from one notable record (in Campbell 1974), of Titahia at Akatore in the far east of Otago (cf. patterns in the living flora of the east coast of Otago).…”

Attention is drawn to the parallel arc patterns permeating much of New Zealand biogeographic structure. The fracturing and creation of such parallel arcs by tectonic movement and erosion has brought about vast disjunctions in many plant and animal groups. The major arcs of distribution correlate with zones of tectonic activity such as plate and terrane margins, fracture zones, and belts of granitic intrusion. Other arcs may be the result of evolution along the Tertiary shores of inland bodies of water. The altitude of many communities in New Zealand also appears to conform to biogeographic and tectonic trends, with higher altitude communities having been derived by the uplift of mid-Tertiary lowland-coastal communities. Evolution is interpreted here as proceeding largely by phases of population reorganisation, for example in the formation of Cretaceous hybrid swarms, and "recrystallisation" in which ancient ranges are "frozen", even in weedy taxa. Such processes correlate spatially with zones of tectonic and physiographic disturbance.

“…The "Torlesse Facies" (Fleming 1970) of the Upper Paleozoic-Mesozoic New Zealand Geosyncline is the largest sedimentary rock unit in New Zealand, yet its sedimentological characteristics are little known. A few interpretative descriptions of local sequences have been published (Webby 1959;Campbell & Force 1972), but three-dimensional studies of detailed facies content and relationships, so essential in meaningful reconstructions of depositional environment(s), have not been made.…”

A small block (S·4km2) of Upper Triassic Torlesse Supergroup rocks is mapped and described. Three sedimentary facies and one probably volcanogenic facies are recognised. They are interstratified and grade laterally into one another.Very thick·bedded sandstone occurs in wedging units up to 450 m thick. It consists mostly of massive, moderately sorted, medium-fine sandstone with scattered zones of parallel lamination, gently inclined lamination, and ripple cross-lamination. Penecontemporaneous black mudstone clasts occur widely. The facies is unfossiliferous.Thin·bedded siltstone forms units up to 95 m thick. It consists of very thin and thin beds of parallel-laminated, small-scale ripple cross-laminated, and deformed cross-laminated, moderately to well sorted coarse siltstone or silty very fine sandstone, alternating with homogeneous or mottled black mudstone. The worm tubes Titahia and T orlessia and feeding trails are widespread.Black mudstone occurs in units up to 150 m thick. It is characterised by discontinuous lamination and dense fine mottling. Very thin interbeds of laminated and cross-laminated fine sand and bivalve shell debris occur at widespaced intervals through the mudstone.Interstratified chert and shale are regarded as volcanogenic. Only one small unit is known in the area.Bedded sandstone, thin-bedded siltstone, and black mudstone are interpreted· to be the products of the distributary-mouth bar, the outer delta front or distal bar, and interdistributary bay, respectively, of a coastal delta. The paleoecologic and paleogeographic implications of this deduction with respect to the Torlesse Supergroup as a whole are discussed.

“…The rocks of the geosyncline are represented by two broad belts of strata of disimilar stratigraphy, sedimentology, and structural style: the Hokonui Facies (Wellman 1956;Fleming 1970) in the west and south, and the Alpine or Torlesse Facies in the east. The two terrains are separated by Haast Schists, metamorphic equivalents of Torlesse Facies rocks into which they pass gradationally.…”

“…A number of studies have established the general stratigraphy of the Hokonui Facies, and detailed geological maps (1: 63,360) are available for parts of this belt (see summary and extensive bibliography in Fleming 1970). Parts of the schist belt are also known in some detail (Grindley 1963, Wood 1963, Means 1963, Brown 1968, but, by contrast, the nonschistose Permian-Jurassic rocks of the Torlesse Facies have been largely neglected, and apart from pioneer studies in the Mt Cook region (Lillie 1962a, 1962b, Lillie and Gunn 1964, Waterhouse 1966, the structure and distribution of rock types within Torlesse Supergroup terrains remains virtually unknown.…”
