多洛线是封闭的地貌洼地，是岩溶系统的地表表现。它们通常是在石灰岩上形成的，也是新喀里多尼亚地貌的典型形态，特别是在主岛的南部地块（被称为massif du Sud）。白云石的特殊之处在于它们在超镁质岩石上发育。它们是橄榄岩溶蚀风化引起的沉降、浸透和塌陷现象的证据。然而，广泛的地下排水系统仍未得到承认。
Dolines are closed geomorphological depressions which are surface manifestations of karstic systems. Usually developed on limestones, they also typify the morphology of the New Caledonian landscape, particularly on the southern massif of the main island (known as Massif du Sud). The specificity of dolines here lies in their development on ultramafic rocks. They are evidences of subsidence, suffosion and collapse phenomena resulting from dissolution weathering of peridotites. However, extensive underground drainage systems are still not yet recognized.
