I veiskjæringene langs Vottvika, 2,5 km nord for ferjeleiet i Andalsvågen finnes det flere kvartsårer og skjærsoner med litt magnetkis i den porfyriske granodioritten. Den gullførende kvartsgangen (Vottvika 2 - hovedforekomst, påvist av NGU) på sørsiden av Vottvika er 10-15 cm tykk og fører mørke striper parallelt ganggrensen. Stripene fører uregelmessig disseminasjon av magnetkis. Analysene antyder tilstedeværelse av sulfosalter og scheelitt. 50 m lenger sør forekomer en rusten skjærsone som er omgitt av en rusten og porøs granodioritt. Langs sonen opptrer svarte kataklasitt-årer og kvartslinser med litt magnetkis (Vottvika, anv. 3). På nordsiden av Vottvika er granodioritten gjennomsatt av svarte, finkornete årer (kataklasittårer) med litt diseminert magnetkis (Vottvika, anv. 1). I veiskjæringen ved Andalsvågen ferjeleie opptrer magnetkis-ankerittårer (str./fall: 216/70) omgitt av serisittomvandlet porfyrisk granodioritt. |

Abstract: | |
The various lithologies are described. These comprise granitic basements rocks of supposed Pre-Cambrian age and Cambro-Silurian supracrustals and intrusives. The intrusives are mostly found within the Bindal and Velfjord massifs. These massifs are younger than the supracrustals, but their mutual age relationship is uncertain. Tectonically the rocks are sitated in "the high metamorphic nappe-complex" of central and western Helgeland. The supracrustal rocks have undergone at least three phases of Caledonian folding, the F2 phase producing the main regional structures. The rocks have mineral assemblages which place them in the almandine-amphibolite metamorphic facies. |
