Bijar volcanic field
volcanic field in Iran
The Bijar volcanic field is a volcanic field northwest of Hamadan in western Iran. It consists of a group of lava domes and cinder/spatter cones that formed during the Miocene and Pleistocene. The main Miocene volcanic features are dacitic and rhyolitic lava domes whereas the cinder/spatter cones and two rhyolitic lava domes are of Pleistocene age. Potassium–argon dating of the Pleistocene volcanic features has yielded ages ranging from 1.3 to 0.5 million years old. The cinder/spatter cones in this Bijar area volcanic field are alkaline in composition.

Why this record matters
The phrase “volcanic field in Iran” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 10, 2026. The linked authority identifier is Q134663099. Authority coordinates are 35.583, 47.800. None of the 1 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
