The Trans-Mexican Volcanic Belt (TMVB), also known as the Neo-Volcanic Axes, is an east-west trending dominantly mafic to intermediate, Neogene and still active, continental volcanic arc. It extends across Central Mexico, from the Pacific Ocean in the west to the Gulf of Mexico in the east. It is over 1,000 km long by 80-230 km wide and spans the states of Nayarit, Jalisco, Colima, Michoacan, Guanajuato, Queretaro, Mexico, DF, Hidalgo, Morelos, Tlaxcala, Puebla, and Veracruz. The TMVB is related to the northeasterly subduction of the oceanic Rivera and Coco Plates beneath the southern edge of the North America Plate (Middle America Subduction Zone).

The topography is characterized by valleys and lakes bounded by volcanoes. The TMVB hosts the tallest peaks in Mexico (> 5,000m), several of which present year-long, snow-capped summits.

The TMVB hosts historical mining districts such as Pachuca-Real del Monte in Hidalgo, and El Oro-Tlalpuhajua in Michoacan-Mexico States. To date, this mining region contains published resources in 15 mining properties, of which 4 are mines and 11 are advanced projects. The TMVB region is currently being explored for some mining companies in search of additional resources.

The image below shows 4 mines in red and 11 advanced projects in blue for a total of 15 mining properties with published resources. In the following weeks more information on the resources and deposit types of the Trans-Mexican Volcanic Belt will be posted.
