How to mount SD card

[mail4asim]

How do I mount the SD card ?   When I try to mount it, I get an error message asking to specify filesystem. When I do that, I get an error message saying invalid filesystem.

Here is some info about my card.
cat  /proc/partitions

Got it working 
Apparently there are two devices in /dev.  I  was using mmcblk0, but it's mmcbk0p1. Once I mounted that, it worked like a charm.

this is the command I used.

mount -t vfat /dev/mmcblk0p1  /mnt/SD

** created a mount point SD in the /mnt.
