The kimberlites are porphyritic with phenocrysts of olivine and smaller amounts of pyroxene, magnetite, ilmenite, pyrope garnet, and/or phlogopite. Winkler (surname), people with the surname Winkler or Winckler Winkler scale, also known as the heat summation scale for classifying climates; Winkler (crater), a crater on the Moon 6473 Winkler, an asteroid; Winkler method, a test to determine dissolved oxygen concentration in water; Winkler vine, an example of large-vine grape culture Drilling over a magnetic anomaly in Winkler Crater, Kansas, has revealed the presence of abundant kimberlite fragments and the absence of key stratigraphic … Figure 4--Aerial photo of the Winkler crater (Brookins, 1970, GSA Bulletin 81, fig.1).
Title: Investigation of Winkler crater, Kansas. The result was that geologists at K-State recommended that Winkler Crater be removed from the list of possible meteorite craters. Impact Crater or Kimberly Pipe? Winkler may refer to: .
Drilling in 1969 revealed a surprise, however—kimberlite fragments. 4, p. 263 - 264 Bibliographic Code: 1969Metic...4..263B.
Kimberlite is an igneous rock, while most Kansas rocks are sedimentary. Another kimberlite was discovered in 1969 by drilling at the Winkler crater site in northern Riley County (fig. Previously, people had speculated that the crater was formed from a meteorite impact (Barringer, 1964; Freeberg, 1966). What's really intersting here is that, coincidentaly, there is an obscure kimberlite formation in Riley County, Kansas (the county where I live) that produced a noticable crater on the surface, called "the winkler crater" near Winkler, Kansas. Authors: Brookins, D. G. Journal: Meteoritics, Vol.
At the surface, the pipes (maars) appear as depressions and several have been mistaken for impact craters in the past - such as the Winkler crater in Kansas. adshelp[at]cfa.harvard.edu The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A 4). Untitled. This field guide covers a half-day tour of three localities representative of the Cretaceous kimberlites of Riley and Marshall Counties in northeastern Kansas: Stockdale, Bala, and Winkler Crater.
