    Whole rock boron and other mobile and immobile element concentrations are reported for the alkaline maar volcanic rocks from the Bakony-Balaton Highland Volcanic Field (BBHVF/Hungary) and for three other geographically distinct maar volcanic fields from diverse tectonic settings (Spain/Canary Islands, Tenerife; New Zealand/Waipiata, Otago; and Mexico/Pinacate, Sonora and Ceboruco Cone Field). Boron concentrations, along with other fluid immobile and incompatible element concentrations are used to study the fluid enrichment of the above mentioned intraplate volcanic materials. The fluid addition was the highest in the Trans Mexican Volcanic Belt (Ceboruco Cone Field), which is associated with recent subduction. The BBHVF also shows high fluid enrichment. The average B content of the Tenerife (Canary Islands) samples (6.4 mu g/g) is similar to that of the BBHVF (6.9 mu g/g). The fluid enrichment is higher in the BBHVF than in the Waipiata Volcanic Field (WVF). The magmatic source regions for all the investigated volcanic rocks were affected by fluid components to different degrees, and, despite the distant relationship to subduction zones, all show evidence of a subduction-derived fluid component.
