Tillites are rocks formed from till, which are glacial deposits.

     Period.

     They are in no way deposited by "flood waters" nor are they
     formed by anything other than glacial activity, and later
     indurated. (What do the Creationism Pseudoscientists mean by
     "flood waters?" Fluvial floodwaters? Lacustrine floodwaters?
     Paludal floodwaters? Or their fictional construct of "Noachian
     Deluge Global Floodwaters?)

     Striations are a general term for preferentially oriented
     longitudinal grooves. Rocks can be striated by glacial movement
     (i.e., "glacial striations"), faulting ("slickensides") or shells
     of organisms can be striated; but this is not the point.

     The point is that glaciers and the alpinoarctic environment produce
     a unique and diagnostic set of depositional morphologies and
     environmental indicators of that glacial depositional
     environment.

     "Flood waters" is such a vague geomorphic term (see above) that
     it is essentially meaningless without some sort of modifier (see
     also above). River flood water deposits differ from lake flood water
     deposits, etc., ad infinitum for any sort of flow from a flood event.

     One key demarcation in this argument, aside from the definitions
     of striae and tillites is that till (whence coemth tillites) is
     a glacial deposit which IS UNSORTED and UNREWORKED by glacial
     meltwater. It is a primary glacial deposit. In no way could
     floodwaters of any kind (which, are, of course, water borne)
     deposit anything as unsorted and unstratified that could
     possibly be so grossly misidentified as till.

     Your personal idea has no scientific merit. Limestones are
     either direct marine chemical precipitates, formed in concert
     with evaporites or the accumulation of untold trillions and
     trillions of microscopic calcareous organisms; which, BTW,
     REQUIRE quiet, deep, and probably anoxic water for long periods
     of time (millions of years) for the accumulations of such vast
     thicknesses of biogenic carbonate rocks known from around the
     globe.
