| Forekomsten ligger ved Straumen. Den tilhører samme draget som Hylla. Det har vært uttak av blokkstein i forekomsten. Kalksteinen har en flattliggende foliasjon som defineres av hvite bånd i en ellers grå kalkstein. Området brukes i dag som industriområde, og mulighetene for ny drift er små. Denne forekomsten er ikke den samme som Hall. |

| Abstract: | |
| Forkortet: Diese Arbeit zerfällt in vier Hauptabschnitte. 1. Über die Geologie des Marmors (S.4-18). 2. Über die wichtigsten Eigenschaften des Marmors, mit besonderer Rücksicht auf die norwegischen Marmorarten daneben über Betrieb usw der Brüche (S. 18-158). 3. Über die wichtigsten norwegischen Marmorfelder, hauptsächlich in der nord- norwegischen Glimmerschiefer-Marmor-Gruppe (S. 159-268); weiter in den Trondheim-schen Schiefern (S. 269-282): im Grundgebirge (S. 282-291); in der Bergen-schen Schiefern (S. 291-296), und Contactmarmor in dem Oslo-Gebiet (S. 296-303). 4. Zum Schluss eine wirthschaftliche über die Marmorproduction der Welt und über die Entwicklung der norwegischen Marmorindustrie. |
