Geological Society of America, Bulletin 94 3 : If the exhumation since the Cretaceous would have exceeded this difference, samples from the footslope area of the range must yield younger, reset ages. Clays and Clay Minerals Sample No. Coeval volcaniclastic rocks are recorded in the Sierra de Varela area, ca. As a result, morphogenetic processes related to base level adjustment of fluvial systems seem to have dominated the present day morphology of the western slope Costa, The monomineralic grains are only a few millimetres in diameter and consist almost exclusively of quartz. The effusive character of the dated basalts is unclear because no robust field evidence for effusion above erosional surface has been reported and they might alternatively comprise a subvolcanic intrusion. Eight samples, mainly from granitic rocks of the crystalline basement were collected along a transect encompassing the western slope and upper parts at the South of the Sierra de San Luis Figs. For location of map extent see figure 2.

    Such significant episode of exhumation and uplift may also be linked to the collision of the Chilenia exotic terrane at the proto-pacific margin of Gondwana Chanic orogeny during the late Devonian Ramos, ; Mpodozis and Ramos, ; Davis et al.

    In Shales and Mudstones II. Rabassa, J. Samples were exclusively taken from clay fault gouges developed in macroscopically muscovite free crystalline host rocks. Note the increase in illite age with increase in grain-size.

    It is important to consider that the analysed grain-size fractions represent mixtures of illite formed at different time and temperature conditions, thus yielding different IC and polytypism. In combination with the fact that Gondwanic sediments were preserved in the Bajo de Veliz region, data presented herein evidence a differential exhumation in the Sierra de San Luis.

    Additionally, this would be represented by a break in the slope in the age-elevation plot Gleadow and Fitzgerald, Journal of South American Earth Sciences 11 3 : Exhumation of the section of the Sierra de San Luis studied here started during Carboniferous times. Further constraints comprise basalts emplaced at higher altitudes in the Sierra de San Luis to the northeast of the study area Fig.

    1. This fact suggests that exhumation related to differential block movement driven by faulting was active at least during Permian times.

    2. All samples were taken from well-developed clay-gouges from small-scale faults in the middle part of the western hillslope Fig.

    3. Using XRD patterns derived from randomly oriented samples, it is possible to quantify the relative amounts of 2M 11M and 1M d illite using a method proposed by Grathoff and Moore
