  • The Schmidt hammer, weathering and rock surface roughness
  • Here, careful measurement of the influence of weathering on rock surface texture is used to elucidate the relationships between weathering, roughness and Schmidt hammer rebound values.
  • The effect of surface texture on the determination of the surface hardness of rock using the Schmidt hammer

  • Measurement and calibration of weathering, using the Schmidt hammer, on wave washed moraines on the Upper Norrland Coast, Sweden
  • This paper presents the method used by the AA., exemplified by Schmidt hammer measurements on a raised boulder-beach in the Nordringa region on the Bothnian Bay coast, and some implications of the method. Several archaeological applications are also
  • Use of the Schmidt test hammer to detect enhanced boulder weathering under late-lying snowpatches
  • Evaluating the Schmidt hammer as a method for distinguishing the relative age of late Holocene moraines : Svellnosbreen, Jotunheimen, Norway

  • The AA. used the Schmidt hammer to assess the relative exposure ages of previously dated Little Ice Age moraines deposited by Svellnosbreen glacier in Jotunheimen southern Norway. Schmidt hammer measurements were taken on moraine surfaces which have
  • been deglaciated for 79–259 years since the Little Ice Age, to reconstruct and date previous snout positions. Dating used a typical linear Little Ice Age age-calibration curve and the ages of unknown surfaces were predicted based on Schmidt hammer
  • measurements with the support of lichenometric dates. Calibrated ages exhibited potential dating errors of 63-103 years years, which were estimated using 95% confidence intervals associated with two control points based on moraines of known ages. Schmidt hammer
  • An evaluation of surface hardness of natural and modified rocks using Schmidt hammer : study from northwestern Himalaya, India
  • Four rock types (quartz mica gneiss, schist, quartzite and calc-silicate) located in the Satluj and Alaknanda valleys were used to test whether a Schmidt hammer can be used to distinguish rock surfaces affected by various natural and man-induced
  • processes like manual smoothing of rock surfaces by grindstone, surface weathering, deep weathering, fluvial polishing and blasting during road construction. Discussion of the Schmidt hammer rebound values, R-Values, and the unconfined compressive strength

  • Il est difficile d'établir des corrélations précises entre la dureté des roches, leur résistance à l'érosion et l'évolution du relief| le marteau-test de Schmidt donne cependant une mesure sûre et rapide.

  • Schmidt hammer (SH) R-values are reported for surface clasts from numerically dated Holocene and Pleistocene fluvial terraces in the South Island of New Zealand. The R-values are combined with previously obtained weathering rind, radiocarbon
  • scaling constants suggest changes in clast weathering rates are primarily affected by climatic (precipitation and temperature) and sedimentologic variables (source terrane petrology). Age uncertainties of ~22% of the surface age suggest that Schmidt hammer
  • The use of the Schmidt Hammer and Equotip for rock hardness assessment in geomorphology and heritage science : a comparative analysis
  • The AA. review here the capabilities of 2 types of Schmidt Hammer (Classic N type and Silver Schmidt BL type) alongside 2 types of Equotip (standard type D and Piccolo) for investigating rock hardness in relation to rock weathering on various types
  • of sandstone and limestone, as well as basalt and dolerite. Whilst the 2 Schmidt hammers and the 2 Equotips show comparable results when tested at 15 individual sites, interesting differences are found between the Equotip and Schmidt Hammer values which may

  • the reduction in Schmidt hammer R-values that followed the rapid colonization by this endolithic lichen of pyroxene-granulite boulders on terrain deglaciated over the last 88 years on the Storbreen glacier foreland, Jotunheimen. The rapid rate of biological
