The Garibaldi Volcanic Belt is a northwest–southeast trending volcanic chain in the Pacific Ranges of the Coast Mountains that extends from Watts Point in the south to the Ha-Iltzuk Icefield in the north. This chain of volcanoes is located in southwestern British Columbia, Canada. It forms the northernmost segment of the Cascade Volcanic Arc, which includes Mount St. Helens and Mount Baker. Most volcanoes of the Garibaldi chain are dormant stratovolcanoes and subglacial volcanoes that have been eroded by glacial ice. Less common volcanic landforms include cinder cones, volcanic plugs, lava domes and calderas. These diverse formations were created by different styles of volcanic activity, including Peléan and Plinian eruptions.

  • The Garibaldi Volcanic Belt is a northwest–southeast trending volcanic chain in the Pacific Ranges of the Coast Mountains that extends from Watts Point in the south to the Ha-Iltzuk Icefield in the north. This chain of volcanoes is located in southwestern British Columbia, Canada. It forms the northernmost segment of the Cascade Volcanic Arc, which includes Mount St. Helens and Mount Baker. Most volcanoes of the Garibaldi chain are dormant stratovolcanoes and subglacial volcanoes that have been eroded by glacial ice. Less common volcanic landforms include cinder cones, volcanic plugs, lava domes and calderas. These diverse formations were created by different styles of volcanic activity, including Peléan and Plinian eruptions. Eruptions along the length of the chain have created at least three major volcanic zones. The first began in the Powder Mountain Icefield 4.0 million years ago. Mount Cayley began its formation during this period. Multiple eruptions from 2.2 million to 2,350 years ago created the Mount Meager massif, and eruptions 1.3 million to 9,300 years ago formed Mount Garibaldi and other volcanoes in the Garibaldi Lake area. These major volcanic zones lie in three echelon segments, referred to as the northern, central, and southern segments. Each segment contains one of the three major volcanic zones. Apart from these large volcanic zones, two large poorly studied volcanic complexes lie at the northern end of the Pacific Ranges, namely Silverthrone Caldera and Franklin Glacier Complex. They are considered to be part of the Garibaldi Volcanic Belt, but their tectonic relationships to other volcanoes in the Garibaldi chain are unclear because of minimal studies. (en)

  • La cintura vulcanica Garibaldi è una cintura vulcanica che si estende in direzione nordovest-sudest nelle Pacific Ranges delle Montagne Costiere, da Watts Point a sud fino al a nord. La catena vulcanica si trova nella parte sudoccidentale della Columbia Britannica, in Canada. Forma il segmento più settentrionale dell'arco vulcanico delle Cascate, che include il Monte Sant'Elena e il Monte Baker. La maggior parte dei vulcani della catena Garibaldi sono stratovulcani dormienti o vulcani subglaciali che sono stati erosi dalla coltre di ghiaccio. Altre tipologie vulcaniche meno comuni includono coni di scorie, neck, duomi di lava e caldere. Queste formazioni differenziate furono create da differenti tipologie di attività vulcanica come l'eruzione di tipo peleano e l'eruzione di tipo pliniano. Le eruzioni lungo la catena hanno creato almeno tre importanti zone vulcaniche. La prima iniziò nel campo di ghiaccio di Powder Mountain circa 4 milioni di anni fa. La formazione del massiccio del Monte Cayley ebbe inizio in questo periodo. Una serie di eruzioni multiple comprese tra 2,35 e 2,2 milioni di anni fa diedero origine al massiccio del monte Meager; le eruzioni tra nel periodo tra 1,3 milioni e 9.300 anni fa condussero alla formazione del Monte Garibaldi e di alcuni altri vulcani nella zona del Lago Garibaldi. Queste zone vulcaniche si trovano in tre settori chiamati rispettivamente segmento settentrionale, centrale e meridionale. Ogni segmento contiene una delle tre più importanti zone vulcaniche. In aggiunta a queste, ci sono due grandi complessi vulcanici poco studiati che si trovano al limite settentrionale dei Pacific Ranges, e precisamente la caldera di Silverthrone e il Franklin Glacier Volcano. Vengono considerati come facenti parte della cintura vulcanica Garibaldi, ma la loro relazione tettonica con gli altri vulcani della catena non è ben chiarita a causa della scarsità degli studi. (it)
