“…7 and 8), which typically represents about 15% of all the grains counted. However, other studies have demonstrated that lithic grain abundance is, in part, a function of grain size (Suttner et al, 1985). Although we show the results as percentages, we realize that to some degree these reflect sandstone grain size.…”

“…Over 80 categories of grain types were devised to record the full quantitative information on coarse-grained rock fragments; also, traditional QFR parameters can thus be easily recalculated from the obtained data set, thus meeting all possible needs (Ingersoll et al 1984;Decker and Helmold 1985;Suttner and Basu 1985;Zuffa 1985). For 24 selected samples, 200 transparent heavy minerals were counted on grain mounts, according to the ribbon-counting or Flett methods (Mange and Maurer 1992).…”

The island of Cyprus represents an excellent site to assess quantitatively petrologic clastic response to actively obducting oceanic sources in order to define an actualistic reference for ophiolite provenance, in terms of framework composition and heavy mineral suites. An improved methodology, an extension of the classic ternary QFL logic to include a wider spectrum of key indexes and ratios, provides an accurate synthesis of modal data and allows differentiation of three main petrographic provinces and at least seven subprovinces. Diagnostic signatures of detritus from various levels of an oceanic lithospheric source, and criteria for distinguishing provenance from suprasubduction versus mid-oceanic ophiolites are also outlined. Modern sands derived from the Troodos Ophiolite contain variable proportions of largely pelagic carbonate to chert, boninite to basalt, diabase to metabasite, plagiogranite to gabbroic, and cumulate grains supplied from progressively deeper-seated levels of the multilayered oceanic crust. Dense minerals are mainly clinopyroxenes (diopside), prevailing over orthopyroxenes (enstatite, hypersthene, clinoenstatite), hornblende, tremolite/actinolite, and epidote. Where serpentinized mantle harzburgites have been unroofed, detritus is markedly enriched in cellular serpentinite grains and enstatite, with still negligible olivine and spinel. Sedimentaclastic sands dominated by chert (Mamonia Province) or carbonate grains (Kyrenia Province) are deposited along the southern and northern shores of the island, respectively. Compositions of Cyprus sands are virtually unaffected by climatic, sedimentary, or anthropic processes; recycling of sandstones from foreign sources is a major process only in the Karpaz Peninsula. Petrographic analysis also provides an independent mean to identify prevalent directions of longshore sand transport.
