I recently found some obsidian rocks in a Mattapoisett, MA woods. They are a very shiny black color with gold inclusions. Extremely hard, and shiny. Thought they were a hard coal but would not burn. Retains heat a long time. Is that an indication of volcanic activity at one time? Lots of iron chunks nearby and buried.
What else can I help you with?
What 2 types of volcanoes are there?
There are three. From smallest to largest, they are: Cinder Cones, Composite Volcanoes (also called Strata Volcanoes), and then Shield Volcanoes.
What is the closest volcano to Massachusetts?
Technically the closest volcano to Massachusetts is Mount Pawtuckaway of New Hampshire. Originally thought to be an impact crater by many in the region, modern geologists determined that it is actually the eroded remnants of a volcano from the Devonian Era and the last eruption probably occurred over 200 million years ago.
Are there any kind of volcanos?
There are three different types of volcanoes. The types of volcanoes are shield volcanoes, dome volcanoes, and also composite volcanoes.
What are three types of volcanoes?
Three types of volcanoes are shield volcanoes, stratovolcanoes (composite volcanoes), and cinder cone volcanoes. Shield volcanoes have gentle slopes and are formed by low-viscosity lava, while stratovolcanoes are characterized by alternating layers of lava and ash. Cinder cone volcanoes are small, steep-sided volcanoes formed by pyroclastic material ejected during eruptions.
What type of vocanoes are there?
There are four main types of volcanoes: shield volcanoes, cinder cone volcanoes, stratovolcanoes (composite volcanoes), and calderas. Each type has distinct characteristics based on their eruption style, shape, and composition.
