Among all possible complications are limits in sample volumes and masses, including possible toxicity or radioactivity and also the legal status of the samples. In this contribution, these problems are addressed by application of microsampling by surface exfoliation of geological objects and archaeologic artifacts using various tapes and subsequent analyses of the resulting samples. Among method used were both optical and electron microscopy. Quick to use portable and stationary methods of optical microscopy is used. Scanning electron microscopy was used with Energy-dispersive X-ray spectroscopy to localize specific 2D surface charts of elemental compositions which response to the surface topography in original samples. Also Raman spectroscopy and X-ray powder diffraction were evaluated. Both methods yield results depending on sample type and experimental setup but are in general usable. The method is validated and operational with some limits and can be marked as vital possible alternative for researchers working in terrain or for obtaining of surface information without damaging of the studied object.
