Basalt is eroded to sand by wind and rain. The sand accumulates in ocean sediment and experiences great pressures over time. After a sufficiently long time, and uplift reveals what had been sand and has become sandstone.
The sandstone layer is older than the basalt. The older rock cannot be on top of the younger rock. The sandstone and the basalt (or basalt dike) are both deposited at the same depth.
Sandstone is the odd one out as it is a sedimentary rock, as opposed to granite and basalt which are respectively felsic and mafic igneous rocks.
Limestone does not belong, as it is primarily composed of calcite, while the other three - shale, sandstone, and basalt - are all composed of different mineral compositions (clay minerals, quartz, and basaltic minerals, respectively).
In the question "which does not belong; shale, basalt, sandstone, or limestone?" the answer is Basalt. Shale, Sandstone, and Limestone are all sedimentary rocks. Basalt is an Igneous rock. Shale and Sandstone are both clastic sedimentary rocks which means they come from the "pieces" or remains of rocks after weathering. Limestone is a chemical sedimentary rock which means it is deposited as a result of a chemical reaction, or a collection of material made by organisms, such as coral. volcanic basalt dykes are molten basalt that rose through existing sedimentary rock, and crystallized when it rose to the surface about 32 million years ago. The magma cools and hardens which creats a basalt stack, resistant to weather. Basalt is a common extrusive volcanic rock.It color is usually gray or close to black.
Shale turns into slate, granite into gneiss.
If the sandstone is below the basalt layer, it is older. Though caution is advised, to make sure it is really a basalt layer and not an intrusion of gabbro. Other indicators that the sandstone is older is evidence of alteration to the sandstone where the two meet (called a "baked contact") and pieces of sandstone being found in the the basalt.

Sandstone is changed into quartzite and basalt is changed into schist or gneiss through the process of metamorphism.

Quartzite is metamorphosed quartz sandstone. Basalt is an extrusive igneous rock.
