'''Siloe Patera''' is a [[Patera (planetary nomenclature)|patera]] in the [[Arabia Terra]] area on the planet [[Mars]]. Lying south of the [[Martian dichotomy]] boundary, it measures {{cvt|30|km}} x {{cvt|40|km}} across.<ref name="esa">{{cite web |title=Siloe Patera |url=https://www.esa.int/ESA_Multimedia/Images/2015/05/Siloe_Patera |publisher=[[European Space Agency]] |access-date=5 October 2022}}</ref> The patera is a collection of deep craters that extend approximately {{cvt|1,750|m}} beneath the Arabia Terra surface. It features scarps, faults and steep crater walls. Extending {{cvt|60|km}} from the southwestern part of the crater are thought to be lava or pyroclastic flows. One of several irregularly-shaped craters in the region, it is thought to be the caldera of a [[supervolcano]],<ref name="Michalski13">{{cite journal |last1=Michalski |first1=J.

The scientists speculated that it is a caldera rather than an [[impact crater]] because of its irregular shape, the absence of a raised rim or central peak, and lack of impact ejecta.<ref name="Michalski13" /> These explosive volcanoes erupted during the planet's first billion years. They are thought to have produced fine-grained sediments that deposited in layers.<ref>{{cite web |last1=Chan |first1=S. |title=New class of volcanoes found from ancient craters on Mars |url=https://theconversation.com/new-class-of-volcanoes-found-from-ancient-craters-on-mars-18831 |website=[[The Conversation (website)|The Conversation]] |access-date=5 October 2022 |date=3 October 2013}}</ref>
