Пожалуйста, помогите перевести "The main tungsten ore body is #10 vein which is fairly regular".

The main tungsten ore body is #10 vein which is fairly regular; 3.4 ft average
width and grades 1% WO3 over a length of at least 2200 feet.

Выражение встречается в следующем контексте:
The main tungsten ore body is #10 vein which is fairly regular; 3.4 ft average width and grades 1% WO3 over a length of at least 2200 feet.

Заранее спасибо

Хорошо бы контекст пошире. regular может означать либо "согласное" (если речь о жиле, внедрившейся по напластованию), либо "правильной формы", либо "выдержанное" (равномерное по мощности, составу, и достаточно длинное) Здесь скорее всего речь о последнем, но надо смотреть.

The main tungsten ore body is #10 vein which is fairly regular; 3.4 ft average
width and grades 1% WO3 over a length of at least 2200 feet. Vein width on
surface varies from two feet to eight feet has been traced for about a mile. The
average dip is 85 degrees east but can locally be as low as 65 degrees. In
several areas the vein splits. A second vein #6 vein is on strike but offset to the
east. Ore shoots appear to plunge at 30 degrees to the north.
