Record #143066:

Non-destructive analysis of morphology, chemical composition and physical properties of large gold nuggets from Finnish Lapland / Kari A. Kinnunen, Bo Johanson, Mauri Terho, Risto Puranen.

Title: Non-destructive analysis of morphology, chemical composition and physical properties of large gold nuggets from Finnish Lapland / Kari A. Kinnunen, Bo Johanson, Mauri Terho, Risto Puranen.
Author(s): Kinnunen, Kari A.
Johanson, Bo.
Terho, Mauri.
Puranen, Risto.
Date: 1997.
In: Geological Survey of Finland. Special Paper. (1997.), Vol. 23 (1997)
Abstract: Several non-destructive methods were tested on large gold nuggets in Inari. 40 nuggets were studied in detail. Morphological analyses examined form, roundness, surface texture and used photmacrography. Chemical analysis used electron microprobe. Physical measurements included mass, volume, density, porosity, magnetic susceptibility, natural remnant magnetism and electric conductivity. Results are tabulated for three largest nuggets. Non-destructive tests that jewellers, traders and connoisseurs can use are suggested.
