Røskingen foregikk ca. 1918. To små røskegrøfter er helt gjengrodd, men like ved er det blottet litt av mineraliseringen. Mm- til noen få cm mektige bånd av massiv finkornet hematitt veksler med bånd av henholdsvis finkornet amfibolitt, epidot og kalkspat (prøve 02, 03 og 04). Båndene er småfoldet med akse 310/30 (omtrentlig pga. ødelagt kompass). Mineraliseringen er blottlagt over en mektighet på ca. 1 m. Lavere i lia er liggbergarten blottet. Det er en urein, konglomeratisk kalkspatmarmor med kvartslinser og tynne klorittlag. Under denne er det kalkspatmarmor (01). Mineraliseringen har sannsynligvis sammenheng med mineraliseringen på Myrvanghaugen i ØSØ.

Abstract:

Oppramsing av hele landets jern-titanforekomster, hvorav 15 trekkes fram som de største. Hver forekomst beskrives ut fra befaring med geologiske og dels kjemiske data. Oppredningsresultater presenteres også. Oppramsing- en går fra Hedmark til Finnmark i nord.
