The phrase "a thin zone of" is correct and usable in written English.
It can be used to describe a narrow area or layer of something, often in scientific or technical contexts.
Example: "The researchers discovered a thin zone of mineral deposits that could indicate the presence of valuable resources."
Alternatives: "a narrow band of" or "a slim layer of".
There are various arrangements of xylem and phloem, but usually a single strand composed of both is surrounded by parenchyma cells, the pericycle (a thin zone of living cells just within the endodermis), and an outer layer of cells with specialized walls, the endodermis.
The Arctic coastal plain north of the Brooks Range, often referred to as the North Slope, has a truly polar environment, with the sea waters along the coast frozen eight months of the year and the ground permanently frozen except for a thin zone of summer melting.
Fingers are created with interfacial perturbations, formed by adding a thin zone of regularly varying hydraulic conductivity along the layer.
A thin border of low signal on T1WI and T2WI is often seen at the inner margin of the lesion corresponding to a thin zone of sclerosis seen on plain films and/or CT.
In the second model, the "surface polymerization" model, chain initiation is assumed to occur in the fluid phase, whereas chain propagation and termination occur in a thin zone on the surface of the polymer particles.
Karst features are concentrated in a thin zone at the top-of-rock, likely representing former epikarst, and also in a thicker zone in the middle of the aquifer.
For example, the moderately acidic environment of the natural ecological niche of H. pylori, a thin zone within the gastric mucus layer with a pH of ∼5.5 6 [21], may damage naked double stranded DNA (e.g. by depurination) before it is taken up by the recipient cell.
Based on the results of the circuit analyses, we defined 'L4' as a thin zone centered on 0.33 (in units of normalized cortical depth) and spanning 0.05 the cortical thickness (i.e., depth range 0.305 0.355).
The fontanels are located at the midline junctions of bregma and lamda, and have a thinner zone in the skull; where the skull is thinner, it is more conductive.
We used a stacking method to obtain three-dimensional distributions of relative reflection strengths of S waves and found a thin planar zone of high reflection strengths at depths of 25 30 km, which we call a S wave reflector.
In particular, the earthquakes are concentrated along a surprisingly thin zone at depths of 40120 km between 21.0°N and 22.5°N (Figs. 6(f), 6(g), and 6(h)), with an apparent thickness of the seismic layer of less than 20 km.
